ABSTRACT:
A liquid crystal display having a plurality of pixels (1), comprising an lower electrode layer (21), a transparent upper electrode layer (13), a liquid crystal layer (10) arranged between the upper and lower electrode layers (13, 21) and an at least partly reflective layer (20, 30), for at least partly reflecting incident light having passed through the liquid crystal layer (10). The reflective layer (20, 30) is electrically isolated from the lower electrode layer (21) and positioned between the liquid crystal layer (10) and the lower electrode layer (21). With this arrangement the DC-component of an electric field in the liquid crystal layer can be eliminated or, at least, considerably reduced, and a flicker-free reflective or transflective LCD thereby realized. Furthermore, flicker is eliminated without having to pay the price of reduced reflectance of the reflective layer and the consequent reduction in display brightness and contrast.
