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.
