Abstract
A fringe field switching liquid crystal display (100) includes a first substrate (101) and a second substrate (110) disposed opposite each other and spaced apart a predetermined distance. A liquid crystal layer (120) is interposed between the first substrate and the second substrate. A plurality of pixel electrodes (104) is formed on the first substrate, the pixel electrodes being parallel to each other. A counter electrode (102) is formed between the first substrate and the pixel electrodes, the counter electrode being overlapped partially by the pixel electrodes. A transparent insulating layer (103) is disposed between the counter electrode and the pixel electrodes. The pixel electrodes are used to reflect light beams. The fringe field switching liquid crystal display can thus utilize ambient reflected light as well as light provided by a backlight, so that the fringe field switching liquid crystal display has low power consumption.
