Patent ID: 7136130

Claim:
A liquid crystal display device comprising first and second transparent substrates and a liquid crystal layer which is sandwiched between the first and second substrates, wherein the first substrate includes a plurality of video signal lines, a plurality of scanning signal lines and a plurality of pixel regions which are formed as regions surrounded by the video signal lines and the scanning signal lines, each pixel region includes at least one active element, one pixel electrode and one common electrode, and color filters are formed between the pixel electrodes and the liquid crystal layer, the improvement being characterized in that the common electrodes are formed as layers above the color filters and the pixel electrodes are formed as layers below the color filters, and the color filters are formed to be superposed on at least the entire surfaces of the pixel electrodes in the pixel regions, portions of the common electrodes function as common signal lines, and the common signal lines are made of transparent conductive bodies and have light shielding layers on the active elements.
