ABSTRACT:
A semitransmissive hometropic liquid crystal display device includes: an active matrix substrate; a counter substrate; a liquid crystal layer interposed between the substrates; and a plurality of pixels. Each pixel is comprised of a reflection section (that performs display in a reflection mode) and a transmission section (that performs display in a transmission mode). The liquid crystal display device further includes an electrode covering (13, 14) configured whereby voltage applied to the liquid crystal layer in the reflection section approximates the voltage applied to the transmission section. The electrode covering film (13, 14) comprises a transparent conductive film which functions as applied voltage adjusting means by compensating for a difference in a work function between the reflecting electrode (5) and the transparent electrode (6).
