发明名称 A display device
摘要 <p>A liquid crystal display device (100) for generating different colours comprises a liquid crystal cell with a front polarizer (1) and a rear polarizer (8), wherein the rear polarizer is optically transmissive, reflective and/or transflective. In the case that the rear polarizer is transmissive or transflective a broad band back light (9) may be provided to improve the image quality. The various colours are generated in the liquid crystal display device by application of an electric field which causes a change in cell retardation. In one embodiment a retardation layer is provided between the front polarizer (1) and the other elements of the liquid crystal cell for generating different colours. &lt;IMAGE&gt;</p>
