Abstract: A display device includes a display unit in which pixels are arranged in a matrix. The pixels each include a first sub-pixel having the largest area among sub-pixels, a second sub-pixel adjacent to the first sub-pixel and having an area smaller than that of the first sub-pixel, and a third sub-pixel adjacent to the first and second sub-pixels, having an area smaller than that of the first sub-pixel, and arranged in the same column as that of second sub-pixels. First, second, and third pixels are aligned in at least one of a column direction or a row direction and each include the first, second, and third sub-pixels that can display different one of first, second, and third colors. Areas of the first, second, and third colors displayable by the first, second, and third pixels in total are equal to one another.

Abstract: In order to increase the transmittance around a pixel and to increase the brightness of the screen in an IPS mode liquid crystal display device, a pixel electrode with a slit is formed on a common electrode through an interlayer insulating film. An opening is formed in the common electrode on the outside of the end portion of the pixel electrode as seen in a plane view. Because of the presence of the opening, the electric field lines from the end portion of the pixel electrode reach the layer above the liquid crystal layer and reach further away from the end portion of the pixel electrode, so that it is possible to increase the control ability to the liquid crystal around the pixel. As a result, the pixel transmittance can be increased as a whole and the brightness of the screen can be increased.
