用化には至つていない。 An electrochromic display device is an application of the phenomenon in which an electrochromic material causes a reversible color change due to an electrode reaction.
Its characteristics such as clear display, low-voltage operation, and no need for maintenance power for display have attracted attention, and efforts are being made to put it into practical use. There are still issues to be resolved, and complete practical application has not yet been reached.

いる。 Electromic display devices are classified into several types depending on the type of electromic material used. Among them, those that use a vapor-deposited layer of metal phthalocyan as the electromic material are low voltage, low power consumption, and have bright colors. Although it is promising in terms of being able to display the test results, there are still some problems, especially the fact that the repeated point reduction life (blinking life) is not long enough, which is a big problem like other types. Attempts have been made to improve or solve this problem by removing as much oxygen as possible from the electrolyte, increasing the purity of the electromic material, and even adding special additives to the electrolyte.
本発明は、この様な問題点を解決する一つの手

ることからも推論される。 That is, the present invention relates to an electrochromic display device (hereinafter referred to as DPC) that uses metal phthalocyanine (hereinafter referred to as DPC) as an electrochromic substance.
(Sometimes abbreviated as ECD), this is an ECD characterized by having a WO 3 vapor deposited layer provided on top of and in contact with the DPC vapor deposited layer. In this case, the WO 3 layer not only serves as a mere protection for the DPC layer, but is also thought to act as a proton conductor that is involved in the coloring of the DPC. It is conventionally known
It behaves completely differently than when only the WO 3 deposited layer is used alone, i.e. there is no coloring of the WO 3 layer, and the required voltage is almost the same as the ECD using only the DPC layer, but when using only the DPC layer This is also inferred from the fact that it has a similar coloration.

2000Å位のものが好ましい。 Hereinafter, the present invention will be explained in more detail based on the drawings. The drawing is a schematic cross-sectional view showing the structure of a typical type of ECD of the present invention, in which a DPC vapor deposition layer 4 is first provided on a transparent electrode 2 on a substrate, and then a WO 3 vapor deposition layer 5 is further provided on top of the DPC vapor deposition layer 4. and add it to electrolyte 6
ECD with structure combined with counter electrode 3 via
It is. Here, transparent electrodes are conventionally known.
Typical examples are SnO 2 and InO 2 , and the electrolyte is usually 0.1NKCl, which is used in WO 3 cells and DPC cells.
An electrolyte solution, typically an aqueous solution, is used.
The WO 3 layer and the DPC layer are each provided by a vacuum evaporation method, and their thickness is not particularly limited, but from a manufacturing and other practical standpoint, they are both 300 Å to 3000 Å.
Items in the Å range are easy to handle, especially from 1000 Å to
A thickness of about 2000 Å is preferable.

体もエレクトロクロミズムを示す。 The most typical DPCs are lanthanide metal phthalocyanines such as neodymium phthalocyanine, erpium phthalocyanine, and lutetium phthalocyanine, and the effect of the present invention can be obtained no matter which one is used, but the color tone may vary slightly depending on the type of metal. is the same as for the DPC layer only. For example, when lutetium phthalocyanine (HLu(PC) 2 ) is used as the DPC, the HLu(PC) 2 layer becomes red when a positive voltage is applied to the display electrode, and becomes blue when a negative voltage is applied. In this case, the blue coloring density is lower than the red coloring density compared to the case where the WO 3 layer is not provided. In addition to lanthanide metals, phthalocyanine complexes such as Cu and Fe also exhibit electrochromism.
次にこの様な構造を持つた本発明のECDの点

寿命であるのに対し、本発明の図面の如きタイプ
のECDの寿命は104〜105回に達した。 Next, the blinking life of the ECD of the present invention with such a structure is compared to that of the conventional DPC ECD without the WO 3 layer.
In comparison, when the lifespan of the product without the WO 3 layer was measured by repeating one cycle of 8 seconds with +2V for 4 seconds and -2V for 4 seconds, it was found that the life of the product without the WO 3 layer was approximately 103 cycles at most. The lifespan of the type of ECD shown in the drawing has reached 10 4 to 10 5 cycles.
以上の如く、本発明によれば従来のECDでは
得られなかつた安定な色採をもち、かつ寿命の比
較的長いECDを得ることが出来た。 As described above, according to the present invention, it was possible to obtain an ECD that has stable color reproduction that could not be obtained with conventional ECDs and has a relatively long life.
