Abstract
Abstract In a method of manufacturing a liquid crystal display device of this invention, a light transmittance of an overcoating layer of the liquid crystal display device is partially reduced to form a part of a light-shielding portion. Therefore, a color filter can be easily formed, and hence the device can be manufactured at high productivity and low cost.
