    摘要： There is no method combining advantages of both an analog gray scale method and a digital gray scale method. An object is to provide a means that can perform display in a plurality of display modes. In a display mode-specific video signal generation circuit, an input video signal is output as an analog value without any change, as a binary digital value, and as a multi-valued digital value. As a result, a display gray scale of a pixel changes in a timely manner. Accordingly, a clear image can be displayed. In other words, an analog signal and a digital signal are switched and input to a source driver. In addition, the display device also includes a means that switches and outputs an analog signal and a digital signal. By using such means, the display device can have the advantages of both the analog gray scale method and the digital gray scale method, thereby achieving the above object.

    摘要： It is an object 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. It is another object to provide a pixel circuit having a function to control a lighting state of a backlight based on each pixel. These objects are achieved by turning off a light-emitting element in display of a black gray scale, and by providing a light-emitting element in each pixel and providing, in a pixel circuit, 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 in each pixel, a light-emitting element that is a backlight is turned off when a black gray scale is displayed, whereby reduction in contrast due to light leakage from a liquid crystal element can be prevented.
