  • Publication number: 20130222747
    Abstract: The present invention provides a display panel capable of suppressing display unevenness caused by the capacitance change due to misalignment when four primary colors are used. The display panel of the present invention includes: signal lines; pixel electrodes; and a common electrode. In the display panel, a single pixel is constituted by picture elements of four or more colors. Each of the pixel electrodes is connected to each one of the signal lines. The pixel electrodes, which are included in the single pixel, are arranged in a squared shape, and include a pixel electrode having larger area and a pixel electrode having smaller area. Both of a signal line connected to the pixel electrode having the larger area and a signal line connected to the pixel electrode having the smaller area overlap with the pixel electrode having the larger area.
