ABSTRACT:
The periphery of a color filter element formed on a transparent glass substrate and the periphery of a pixel electrode formed on the color filter element are made to overlap with gate lines and drain lines. Black matrices are formed between adjacent color filter elements, on neighboring color filter elements, and on pixel electrodes. In this case, the opening of the black matrix slightly encroaches upon the gate lines and the drain lines. As a result, the area surrounded by the gate lines and the drain lines minus the area for forming a thin film transistor therein is made wide. Accordingly, the opening factor of a liquid crystal display device is made large.
