Abstract

A display device includes: a liquid crystal display panel; and a driver circuit that drives the liquid crystal display panel. The liquid crystal display panel includes a liquid crystal layer, pixel electrodes provided in a region facing the liquid crystal layer and which apply a voltage thereto, and a phase difference layer and a polarizing plate each provided on a side, relative to the liquid crystal layer, which ambient light enters. Each of the pixel electrodes includes a plurality of partial electrodes, and the driver circuit selects one or more partial electrodes from the partial electrodes to which a constant voltage is to be applied in accordance with an image signal. The constant voltage causes the liquid crystal display panel to be in a white state. The driver circuit performs gray-scale display by modulating lighting area of each pixel at a frame rate of less than 60 Hz.
