ABSTRACT:
A plurality of pixels are arrayed in a matrix format on the liquid crystal panel of a liquid crystal display. GH liquid crystal layers and transparent electrodes for displaying a plurality of different colors are alternately stacked on a reflecting plate, and therefore each pixel has three liquid crystal layers. Pieces of potential information supplied to the respective liquid crystal layers are controlled by switching elements connected to signal lines and scanning lines. The signal lines and the scanning lines are respectively connected to driving ICs, which are connected to a signal processing circuit. In each pixel, while the potential information of one liquid crystal layer is controlled, the remaining liquid crystal layers are set in a floating state.
