DISPLAY DEVICE AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a display device in which a problem of light leakage from a liquid crystal element in black display is reduced or overcome and the contrast is improved, and provide a pixel circuit having a function to control the lighting state of a backlight for each pixel.SOLUTION: A light-emitting element is turned off in display of a black gray scale. A light-emitting element is provided in each pixel and a pixel circuit has a function to individually control lighting and non-lighting of the light-emitting element depending on a gray scale to perform display. When a backlight is provided corresponding to each pixel, a light-emitting element that is a backlight is turned off when a black gray scale is displayed, so that reduction in contrast due to light leakage from a liquid crystal element can be prevented.
