Abstract

The target of this invention is to provide a display device in which a viewing angle characteristic is improved by providing a plurality of sub-pixels to one pixel. Alternatively, to provide a display device in which an aperture ratio is suppressed even when a plurality of sub-pixels is provided. A pixel including first sub-pixel, a second sub-pixel, and a third sub-pixel, a scanning line, a signal line, a first capacitor wiring, a second capacitor wiring and a third capacitor wiring are provided. Pixel electrodes each electrically connected to one electrode of the first to third capacitor elements, and the first to third capacitor wirings, respectively, are provided to the first to third sub-pixels electrodes, respectively. Potentials of the first capacitor wiring and the second capacitor wiring are changed and a potential of the third capacitor wiring is kept almost constant.

Description

technical field [0001] The present invention relates to a thing, a method, or a method of making a thing. In particular, the present invention relates to a display device or a semiconductor device. More specifically, the present invention relates to a display device provided with a plurality of sub-pixels in a pixel. Background technique [0002] In recent years, thin display devices such as liquid crystal display devices have been widely used in displays of mobile phones, TVs, and the like. In particular, liquid crystal display devices have excellent characteristics such as high definition, thin profile, and low power consumption, and their market scale is expanding. On the other hand, there is an increasing demand for enhancement of the functions of these display devices, for example, liquid crystal display devices with wide viewing angles and high image quality are expected. [0003] As a technique for improving the viewing angle characteristics, a method of improving ...
