| 摘要 |
This invention relates to a liquid crystal display device, comprising at least one retardation film (4), a nematic liquid crystal layer (5), and a light reflecting RGB patterned cholesteric colour filter (6), for reflecting either essentially left-circular or right-circular polarised light, being characterised in that said liquid crystal layer (5) is a super twisted nematic liquid crystal layer having a twist angle in the interval 180-270 degrees, and in that the summed retardation R of the retardation film or retardation films and the liquid crystal layer is equal to approximately R=(3+2n)lambda/4, where n=0,1,2,3.
