Abstract:
A LCD device containing an active drive dot matrix LCD element, each pixel containing subsidiary pixels each having a color filter; a passive drive segment display LCD element laminated on rear side of the active drive LCD element, having segment electrode, arranged to be applied with a set voltage, the segment electrode having edge defining a segment shape; cross-nicol polarizers disposed on both outer sides of the LCD elements; controller circuit including first part controlling voltages to be applied to subsidiary pixels, and second part controlling voltages to be applied to the segment electrode; wherein the display device produce normally black display in the absence of applied voltage; and wherein when the segment electrode is activated, those subsidiary pixels in pixels outside the edge of the activated segment electrode are partly driven and partly not driven, displaying different color or intermediate grade, than the conventional art.
