ABSTRACT:
A CF on TFT type liquid crystal display and a method of manufacturing the same. The liquid crystal display has a plurality of parallel scanning lines, a plurality of parallel data lines which cross the scanning lines, thin film transistors each disposed in the proximity of an intersection between one of the scanning lines and one of the data lines, and pixel electrodes disposed in a matrix and each coupled with one of the thin film transistors. The light shield film is formed over areas including at least the thin film transistors but except over portions which become banks and hinder flow of developer for patterning the light shield film. As an embodiment, the light shield film can be formed along the data lines, and also partially along the scanning lines except a part of each portion of the scanning lines between adjacent data lines.
