Abstract

A liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer, and a plurality of pixels. Each of the pixels has a reflection region for performing display in a reflective mode. The first substrate includes a pixel electrode provided in each of the pixels and a reflection layer positioned opposite to the liquid crystal layer with respect to the pixel electrode. The reflection layer has a first region positioned in each of the pixels and a second region positioned between any two pixels adjacent to each other. Voltages of an identical polarity are applied to the liquid crystal layer for any two pixels adjacent to each other in a row direction, for any two pixels adjacent to each other in a column direction, or for all the pixels.
