摘要：
A liquid crystal display device includes a pair of substrates with a liquid crystal layer therebetween with a plurality of scanning signal lines and of video signal lines being formed on a first substrate. The scanning and video signal lines are arranged in a shape of a grid, and a pixel region is defined as a region surrounded by the scanning and video signal lines. A black matrix is formed on a second substrate, is arranged in a position overlapped on the scanning and video signal lines, and has an opening portion in each pixel region. A plurality of first electrodes are provided on the first substrate, and a plurality of second electrodes are provided on the second substrate, wherein at least one of first electrodes and at least one of the second electrodes are arranged in a position overlapped with the opening portion.
