Abstract:
A transflective Liquid Crystal Display device has a liquid crystalline (LC) cell with reflective portions (101 R) and transmissive portions (101 T). The LCD device has a dual cell-gap design, the cell gap (dT) for the transmissive portions differs from the cell gap (dR) for the reflective portions. According to the invention, this cell gap difference is effected by means of an optical retarder (120) inside the LC cell. A thickness of said optical retarder (120) is such as to compensate the difference in cell gaps. Preferably, the optical retarder is a patterned retarder extending essentially only over the reflective portions (101 R) of the cell, and having quarter wave retardance.
