Abstract
There is a problem in that, in a liquid crystal display panel in which a color filter is formed on an opposing substrate, it is necessary to assemble an element substrate and the opposing substrate by extremely high precision position alignment, and when this precision is low, the aperture ratio decreases and the display becomes darker. With the present invention, red color filters (R) are formed on driving circuits (402, 403), peripheral circuits, and a color filter (405d) for protecting a pixel TFT portion (407) is formed for each pixel.
