Abstract

A pair of lightly doped drain (LDD) regions are provided in a thin film transistor of each pixel of a thin film transistor substrate for a liquid crystal display device and a light shielding portion of a material having reflectivity lower than that of a metal and covering a portion or a whole portion of the LDD regions is provided so as to restrict an internal random reflection of light.
