Patent ID: 7978165

Claim:
A liquid crystal display device comprising: a plurality of pixels arranged in a matrix, adjacent to each other row-wise and column-wise; a plurality of gate bus lines extended row-wise and connected to the pixels arranged row-wise; a plurality of drain bus lines extended column-wise and connected to the pixels arranged column-wise; and a plurality of auxiliary capacitor bus lines extended row-wise, connected to the pixels arranged row wise and not connected to the gate bus lines, said plurality of the pixels each including: a pixel electrode; an auxiliary capacitor electrode connected to the pixel electrode, the auxiliary capacitor bus line and the auxiliary capacitor electrode forming an auxiliary capacitor; a first switching element connected to the pixel electrode and the drain bus line, for controlling the connection between the pixel electrode and the drain bus line by the gate bus line; and a second switching element having a first electrode connected to the drain bus line and a second electrode overlapping the pixel electrode with an insulating film formed therebetween, for controlling the connection between the first electrode and the second electrode by the auxiliary capacitor bus line; wherein the second electrode of the second switching element of at least one of said plurality, which is normally operative is not electrically connected to the pixel electrode, and the second electrode of the second switching element of the at least one of said plurality of the pixels, which is not normally operative is electrically connected by laser repair to the pixel electrode at a region where the second electrode overlapping the pixel electrode with the insulating film formed therebetween.
