Abstract
An electrochromic display device comprises a display electrode, a counter electrode spaced from the display electrode, an electrolyte filled in the space between the display electrode and the counter electrode, and an electrochromic coloring layer formed on the display electrode to constitute a display section. That surface of the coloring layer which contacts the electrolyte has a higher density than that of the remaining portion. Preferably, both surface portions of the coloring layer which contact the electrolyte and the display electrode, respectively are more dense than the remaining portion.

An electrochromic display device comprising:
- a display electrode;
- an electrochromic coloring layer formed on the display electrode to constitute a display section and having a first surface portion in contact with the display electrode and a second surface portion;
- a counter electrode spaced from the display electrode;
- and
- an electrolyte within the space between the display section and the counter electrode, the electrolyte being in contact with the second surface portion of the electrochromic coloring layer;
- the second surface portion of said coloring layer which contacts the electrolyte having a higher density than that of the remaining portion of the electrochromic coloring layer.
