Abstract

A color LCD device has a liquid crystalline cell arranged between a front substrate (111) and a rear substrate (112). The device further comprises a color filter (120) having regions (R, G, B) associated with the primary colors of the LCD. For improving the contrast ratio and brightness of the LCD, the device also includes a retarder layer (101). According to the invention, the retarder layer (101) is patterned and has portions (102R, 102G, 102B) of different retardation, which portions are associated with the primary colors of the LCD. Preferably, the retarder layer is a quarter wave retarder. A preferred manufacturing method is based on manipulating the order parameter of a liquid crystalline mixture, whereby at different process temperatures the birefringence value for a portion of the layer is fixed by polymerizing the mixture within said portion.
