Liquid crystal display device

摘要

In a color liquid crystal display device, two capacitors (18, 19) are both connected in parallel between a pixel signal line (4) and an electrode (2a) of a liquid cell (2), or one of the capacitors is connected therebetween, or none of the capacitors are connected therebetween, in order to selectively set a potential (V2) of the electrode (2a) of the liquid crystal cell (2) in four steps. Therefore, gradation display in four steps can be performed without a digital-to-analog conversion circuit, so that the cost of the device can be reduced. <IMAGE>
