Abstract:
1. A liquid crystal display device including a plurality of picture elements, comprising: a liquid crystal panel including first and second substrates arranged opposite to each other and a liquid crystal layer formed of a liquid crystal, which is filled in a space between the first and the second substrates and has a negative dielectric anisotropy; first and second polarizers arranged with the liquid crystal panel interposed therebetween; a first quarter wave plate placed between the liquid crystal panel and the first polarizer; a second quarter wave plate placed between the liquid crystal panel and the second polarizer; a plurality of picture elements and a plurality of color filters; and an optical compensation layer provided between the first and second quarter wave plates, wherein the optical compensation layer includes a plurality of regions for each picture element corresponding to each color filter, wherein the regions in each picture element have different compensation capabilities Rth in a thickness direction respectively.
