摘要:
Multicolor display elements are disclosed that are adapted to full color electric papers, which comprises a display electrode, counter electrode, electrolyte, and display layer, wherein the counter electrode is disposed oppositely to the display electrode, the electrolyte is filled into a space provided between the display electrode and the counter electrode, the display layer is disposed on the surface, which faces the counter electrode, of the display electrode, the display layer contains plural electrochromic compositions in a condition that the plural electrochromic compositions are separated into plural layers within the display layer or are mixed together within the display layer, and at least one of threshold voltage for coloring condition and threshold voltage for decoloring condition, or at least one of charge amount required for coloring into a sufficient color density and charge amount required for sufficiently decoloring, are substantially different each other between the plural electrochromic compositions.
