The housing 40 has a box-like shape in which one surface is opened, and the area of the surface (opposing surface) opposite to the opening surface is smaller than the area of the opening surface. The transparent surface material 100 with a display device of the present invention can prevent a person from grasping the housing 40 , hanging or any hooks from being caught by the housing 40 because the shape of the housing 40 is as described above. As a result, external force can be prevented from being applied from various directions, and the housing 40 fixed to the transparent surface material 10 is not easily detached.

  As for the housing 40, it is preferable that the upper surface 41 has a slope. If the upper surface 41 has an inclination, it becomes difficult to apply a force from the outside in the direction of gravity, and the casing 40 can be significantly prevented from being detached from the transparent surface material 10.

  The shape of the slope of the upper surface 41 of the housing 40 is not limited. The specific example of the cross-sectional shape of the upper surface 41 of the housing 40 is shown in FIG. FIG. 3 is an enlarged view of the top surface 41 of the housing 40, showing that the top surface 41 is straight (a), curved (b or c), or a combination of flat and inclined (d or e).

  It is preferable that the said inclination of the housing 40 is 15 degrees-45 degrees in the downward direction (opposite to a Y direction) on the basis of the perpendicular direction (Z direction) of the transparent surface material 10. The angle is calculated based on the starting point of the inclination of the housing 40. For example, as shown in (a), (b), (c) or (e) of FIG. 3, when the casing 40 is inclined from the junction point with the transparent surface material 10, the junction point is the starting point I assume. On the other hand, as shown in (d) of FIG. 3, when the flat surface is flat by a predetermined length from the junction point of the casing 40 and the transparent surface material 10 and the slope starts after the predetermined length, (For example, point d1 in FIG. 3d) is a starting point. If the angle of inclination is in the above range, even if an object (for example, a can of drinking water etc.) is placed on the housing 40, it has an effect of being not fixed and being able to be dropped. 20-40 degrees is preferable and, as for the said angle of the inclination of the upper surface 41 of the housing 40, 30-35 degrees is more preferable.

  It is preferable that the housing 40 has a slope other than the upper surface 41. The angles of inclination of the surfaces other than the upper surface 41 are the same as in the case of the upper surface 41. The angles of the other surfaces are all based on the vertical direction of the transparent surface material 10, if it is the left surface of the casing 40, it is the right direction, if it is the right surface of the casing 40, it is the left direction. It is the value measured against.

  The opening surface of the housing 40 is fixed to the transparent surface material 10. The method of fixing the casing 40 to the transparent surface material 10 is not limited.
