Patent ID: 7538829

Claim:
An active matrix type liquid crystal display device comprising: a pair of substrates with liquid crystal layer there between; a plurality of common voltage signal lines and a plurality of drain signal lines which crossing each other formed on one of the pair of substrates; a semiconductor layer formed above a forming layer of the common voltage signal lines and under a forming layer of the drain signal lines; a pixel electrode formed in each pixel region on the one of the pair of substrates and electrically connected to one of the drain signal lines; wherein the semiconductor layer has parallel edges and slant edges with respect to said one of the drain signal lines, and edges of the pixel electrode facing toward neighboring edges of the semiconductor layer in a crossing region where said one of the drain signal lines crossing with one of the common voltage signal lines are shaped substantially conforming with the neighboring edges of the semiconductor layer to minimize change of distance between the semiconductor layer and the pixel electrode.
