Abstract
An electrochromic display device is disclosed which utilizes a display substrate having a transparent substrate and a display electrode formed on the substrate which is to be displayed by an electrochromic material. A counter substrate is provided with a counter electrode which faces the display electrode and is spaced therefrom. An electrolyte is provided in the space between the display electrode and the counter electrode. The device is structured such that the counter substrate has through-holes as well as a conductive material which extends through each of the through-holes and is in direct contact with a transparent electrode on the display substrate so that the transparent electrode of the substrate is conductively connected to the electrode on the rear side of the counter substrate.
Claims7
An electrochromic display device which comprises:
- a display substrate comprising a transparent substrate and a display electrode formed on the substrate for display by an electrochromic material;
- a counter substrate provided with a counter electrode facing said display electrode with a space therefrom;
- and
- an electrolyte in the space between the display electrode and the counter electrode,
- wherein the counter substrate is provided with through-holes, and a conductive material extends through each through-hole and is in direct contact with a transparent electrode of the display substrate so that the transparent electrode of the display substrate is conductively connected to an electrode on the rear side of the counter substrate,
- wherein the counter substrate has a recess to receive the electrolyte and protrusions, with said through-holes, are formed in the recess, and the top of each protrusion is conductively connected to the transparent electrode of the display substrate.
