Description

ABSTRACT:
An all solid type electrochromic display device comprises first and second conductive layers and sandwiched between them, at least, an electrochromic layer of tungsten oxide and a solid electrolyte layer. The tungsten oxide of the electrochromic layer has an absorption spectrum, as measured by FT-IR, which meets the following formulae (A) and (B): ##EQU1## wherein A1400, A1800, A2500 and A4000 and A3400 respectively represent the absorbance of 1400cm.sup.- 1800cm.sup.-1, 2500cm.sup.-1, 4000cm.sup.-1 and 3400cm.sup.-1 and A* represents the highest absorbance within a range from 1600cm.sup.-1 to 1650cm.sup.-1. The electrochromic display device is produced by vacuum depositing the tungsten oxide electrochromic layer on another layer.
