Purpose is to realize a display device of high definition and high response speed. The structure is as follows. A liquid crystal display device including: scanning lines extending in a first direction and being arranged in a second direction, video signal lines extending in the second direction and being arranged in the first direction, and a pixel being surrounded by the scanning lines and the video signal lines, in which a pixel electrode is formed in the pixel, the pixel electrode includes a first portion including comb electrode, a second portion including contact portion to receive electrical signal, and a third portion, the third portion protrudes toward an adjacent pixel electrode compared with the first portion and the second portion, and a normal of a side toward the adjacent pixel electrode of the third portion intersects with the first direction and the second direction with an angle other than 0 and 90 degrees.
