    摘要： A display device includes a display section in which a plurality of pixels are arrayed in a matrix, a plurality of scan lines which select pixels, a plurality of signal lines which supply image signals to the selected pixels, and color filters that are arranged so as to correspond to color displays of the pixels. In the device, the display section includes an effective pixel portion and a frame portion that surrounds the effective pixel portion, and the frame portion and a wiring circuit of the effective pixel portion are covered with light-shielding layers, the light-shielding layers being separated from each other at a certain separation location in the display section, and a plurality of color filters having different colors are arranged by being stacked at the separation location.

    摘要： 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.
