Title: Electrochromic display element
Inventor: YOKOYAMA MEISOU
IPC: G02F1/1524
Filed: 1981-10-28
Abstract: PURPOSE:To obtain an EC display element which permits setting of optical colors according to purposes of use by providing display electrodes and a counter electrode, providing transition metallic oxides as an EC layer between the transparent electrode films and a solid insulating layer, and heat-treating the same at prescribed temps. CONSTITUTION:Transparent display electrodes 2 of ITO films or the like are provided on a transparent glass substrate 1. For example, WO3 is selected from EC materials which are transition metallic oxides such as WO3, V2O5, MoO3, TiO2, and is vacuum-deposited to provide a coloring layer 3. Thereafter, said layer is treated under heating for 5 minutes at 300-400 deg.C to form a white- colored thin film. A solid insulating layer 4 (CaF2) is provided thereon and a counter electrode 5 formed with Au is laminated on this layer, whereby an EC display element is obtained. If positive potential is applied on the electrodes 2, the heat-treated WO3 coloring layer 3 generates the wavelength-transmittance characteristics changing from transparency to a pale yellow color. Even when not only the layer 3 but a V2O5 layer is used, the original color changing arises. Thus the EC display device having more variety in colors than in the prior art is obtained by using the transition metal oxides.
