Abstract

PURPOSE:To execute an analog/digital composite display on the same display part, by installing a digital electrochromic display part in an analog display part. CONSTITUTION:On a white number plate 21 of a pointer type analog diaplay part 11, a 7 segment transparent conductive film 22 and an insulating film 23 are formed by means of vapor-deposition and etching. When EC substances 24 and 25 are laminated on them and also a common electrode film 26 is formed, a digital display part 12 by all fixed type electrochromic display of a transparent member is formed easily since a passive reflector, etc. are unnecessary. According to this constitution, the analog/digital composite display is executed on the same place without providing a separate display part.
