Abstract:
1. A transmission-reflection type liquid crystal display device, comprising: a first transparent substrate; a second transparent substrate; a liquid crystal layer between the first transparent substrate and the second transparent substrate; a linear polarizer on the second transparent substrate; a cholesteric liquid crystal polarizer on an outer side of the first transparent substrate, the cholesteric liquid crystal polarizer including a right handed helical cholesteric liquid crystal having a range of pitch values of (380 nm-800 nm)/n, where n is an average index of refraction of the cholesteric liquid crystal; and a reflecting film on an inner side of the first transparent substrate adjacent to the liquid crystal layer, the reflecting film functioning as a pixel electrode and defining a light-transmitting region, wherein said light transmitting region is disposed between an inner edge of a gate line and a side of an outer edge periphery of said reflecting film and between an inner edge of a data line and a side of an outer edge periphery of said reflecting film in each pixel, a first opposing side of said reflecting film overlapping more than half the width of an adjacent gate line, and a second opposing side of said reflecting film overlapping more than half the width of an adjacent data line.
