Patent ID: 7986289

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate opposed to the first substrate; a liquid crystal sandwiched between the first substrate and the second substrate; and a plurality of pixels; wherein the first substrate includes a gate signal line, a first drain signal line, a second drain signal line which is different from the first drain signal line, an insulating film, a conductive layer and a first opaque layer, the gate signal line crosses the first drain signal line and the second drain signal line, the insulating film is formed between the first substrate and the first drain signal line and between the first substrate and the second drain signal line, the gate signal line, the conductive layer and the first opaque layer are formed between the first substrate and the insulating film, the plurality of pixels includes a first pixel and a second pixel which is adjacent to the first pixel, the first pixel includes a first switching element and a first transparent pixel electrode which is supplied with a video signal from the first drain signal line via the first switching element, the second pixel includes a second switching element and a second transparent pixel electrode which is separated with the first transparent pixel electrode and is supplied with a video signal from the second drain signal line via the second switching element, the first pixel is arranged at a first side of the first drain signal line and the second pixel is arranged at a second side of the first drain signal line which is opposite to the first side of the first drain signal line, the conductive layer is formed along the first drain signal line and is overlapped with the first drain signal line when viewed perpendicularly, the insulating film insulates the conductive film from the first drain signal line, the gate signal line is insulated from the conductive layer, the first opaque layer is insulated from the conductive layer, the gate signal line, the first drain signal line, the second drain signal line, the first transparent pixel electrode and the second transparent pixel electrode, and the first opaque layer is formed along at the second side of the first drain signal line such that the first opaque layer is departed from the conductive layer, and that the first opaque layer is overlapped with the second transparent pixel electrode along an extending direction of the first drain signal line.
