ABSTRACT:
Transflective liquid crystal display device (100.200) comprising a set of polarisers and compensators sandwiching a liquid crystal layer (15) of parallel alignement type, designed for the purpose of improving the viewing angle characteristics of the device, in particular the dark state (voltage on-state) and the contrast. In the reflective part, the arrangement of optical elements consists of a polariser (11), a (biaxial or uniaxial) first retarder (12), a (biaxial of unaxial) second retarder (13), a negative uniaxial third retarder (14) and a liquid crystal cell (15) with well defined orientations of the respective optical axes to each other. In the transmissive part, the arrangement of retarders and polariser as arranged on the viewer side is repeated in reverse order on the backlight side of the liquid crystal device.
