Title: In-plane field type liquid crystal display device comprising liquid crystal molecules with more than two kinds of reorientation directions

Abstract: A liquid crystal display device includes a pair of substrates sandwiching of a liquid crystal layer, plural scanning signal lines and plural video signal lines formed on one of the pair of substrates, and plural pixel regions formed as an area surrounded by an adjacent two of the plural scanning signal lines and an adjacent two of the plural video signal lines. At least a pixel electrode is formed on the one of the pair of substrates in each of the pixel regions, a plurality of counter electrodes is formed on one of the pair of substrates in each of the pixel regions, and at least a counter voltage signal line connects the counter electrodes formed on one of the pair of substrates. The counter voltage signal line is arranged in an overlapping relation with at least one of the scanning signal lines in plan view.
