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 turning-on/off of the light-emitting element depending on a gray scale for display. Since a backlight is provided corresponding to each pixel, a light-emitting element to be a backlight is turned off in display of a black gray scale, to prevent reduction in contrast due to light leakage from a liquid crystal element. |
