As these pattern phase difference layers 39 and 44, phase difference regions 39a, 39b, 44a, and 44b as a plurality of regions in which both or one of the in-plane slow axis and the phase difference are different may be provided. Various modes can be adopted as modes in which the in-plane slow axes and phase differences of the phase difference regions 39a, 39b, 44a, and 44b are made different. For example, the direction of one in-plane slow axis of the adjacent phase difference regions 39a, 39b, 44a, and 44b is orthogonal to the direction of the other in-plane slow axis, the birefringence is different, or the adjacent phase difference regions 39a, 39b, 44a, and 44b are adjacent to each other. For example, the phase difference regions 39a, 39b, 44a, and 44b may have different thicknesses.

  Further, the pattern retardation layers 39 and 44 may be configured such that a plurality of retardation regions 39a, 39b, 44a, and 44b are repeatedly provided in a stripe shape with a constant interval. In the present embodiment, the first and second phase difference regions 39a and 44a and the second phase difference regions 39b and 44b are alternately provided in stripes on the pattern phase difference layers 39 and 44, respectively. In addition, the phase difference regions 39a, 39b, 44a, and 44b are configured to be provided in a plurality of rows in the panel width direction that is substantially along the moving direction of the movable plate 40. That is, the extending direction of these phase difference regions 39a, 39b, 44a, and 44b is configured to be a vertical direction that is a direction orthogonal to the panel width direction. That is, these phase difference regions 39a, 39b, 44a, 44b are formed in a rectangular shape that is long in the vertical direction when viewed in the panel thickness direction.

  As shown in FIG. 2B, when the movable plate 40 is arranged so that the phase difference regions 39a, 39b, 44a, and 44b of the movable plate 40 and the fixed plate 35 correspond to each other, the transparent plate 40 is transparent. It is in a state where light can be emitted. That is, the first phase difference region 39a of the fixed plate 35 and the first phase difference region 44a of the movable plate 40 overlap in the panel thickness direction, and the second phase difference region 39b of the fixed plate 35 and the second position of the movable plate 40 are overlapped. The movable plate 40 is disposed at the light transmitting position so that the phase difference region 44b overlaps in the panel thickness direction. Thus, when the movable plate 40 is set to the translucent position, light incident from one side in the panel thickness direction is one polarizing layer 38, one pattern retardation layer 39, the other pattern retardation layer 44, and the other polarization. The layer 43 is transmitted while being linearly polarized or circularly polarized. That is, a bright state is obtained on the other side in the panel thickness direction.

  If the movable plate 40 is arranged so that the phase difference regions 39a, 39b, 44a, 44b of the movable plate 40 and the fixed plate 35 are shifted from each other as shown in FIG. A light transmission (light shielding) state is established. That is, the first retardation region 39a of the fixed plate 35 and the second retardation region 44b of the movable plate 40 overlap in the panel thickness direction, and the second retardation region 39b of the fixed plate 35 and the first position of the movable plate 40 are overlapped. The movable plate 40 is disposed at the light shielding position so that the phase difference region 44a overlaps in the panel thickness direction. When the movable plate 40 is set to the light shielding position in this way, light incident from one side in the panel thickness direction can be applied to one polarization layer 38, one pattern phase difference layer 39, and the other pattern phase difference layer 44 by linearly polarized light or circular light. Although the light is transmitted while being polarized, it cannot be transmitted through the other polarizing layer 43 and is in a light shielding state. That is, the other side in the panel thickness direction is in a dark state.

The width dimension of each phase difference region 39a, 39b, 44a, 44b may be an appropriate dimension so as to obtain a desired dimming state while reducing the moving distance of the movable plate 40. That is, if the width dimension of each phase difference region 39a, 39b, 44a, 44b is too large, it is necessary to move the movable plate 40 greatly. On the other hand, if the width dimension of each of the phase difference regions 39a, 39b, 44a, and 44b is made too small, the moving distance of the movable plate 40 can be reduced, but there is a tendency that misalignment between patterns tends to occur. From such a viewpoint, the width dimension of each of the phase difference regions 39a, 39b, 44a, 44b may be about 5 mm to 30 mm, and preferably about 10 mm to 20 mm.
In addition, the gap dimension along the thickness direction between the fixed plate 35 and the movable plate 40 is such that the movable plate 40 can be moved and the dimming function is not hindered, and the thickness direction can be made compact. It is good also as an appropriate dimension. For example, the gap dimension along the thickness direction between the fixed plate 35 and the movable plate 40 may be about 0.1 mm to 5.0 mm, and preferably about 0.5 mm to 2.0 mm. In addition, the gap dimension along the thickness direction between the translucent plate 34 and the movable plate 40 may be set to an appropriate size in the same manner.

2B and 3B show an example in which light is incident from the fixed plate 35 side, but light is incident from the movable plate 40 side, that is, the translucent plate 34 side. Even in this case, the transmitted light can be adjusted.
Further, the light control layers 37 and 42 in the fixed plate 35 and the movable plate 40 are not limited to the above-described examples, and various other modifications are possible. For example, the phase difference regions 39a, 39b, 44a, and 44b may be provided in a plurality of rows in the vertical direction, instead of being provided in a plurality of rows in the panel width direction. In this case, as will be described later, the moving dimension in the vertical direction of the movable plate 40 that is moved so as to draw an arc while being supported by the suspension arm 28 may be an appropriate dimension. In addition, as the fixed plate 35 and the movable plate 40, other known light control plates can be employed. For example, it is good also as what was set as the structure which provided the light control layer in which the opaque part and the transparent part as a some area | region were formed in pattern shape.
