Abstract: A liquid crystal display device includes a liquid crystal between a TFT substrate including pixels formed in a matrix, and a counter substrate. A pixel electrode is formed in an area surrounded by scanning lines and video signal lines. A common electrode is formed in a lower layer of the pixel electrode through an interlayer insulating film. A long side of the pixel electrode of a first pixel is inclined at a first angle clockwise at a right, angle to the extending direction of the scanning line. A long side of the pixel electrode of a second pixel is inclined at the first angle counterclockwise at a right angle to the extending direction of the scanning line. The liquid crystal is a negative type liquid crystal. Further, a protrusion formed in the long side of the pixel electrode has a side parallel to the extending direction of the scanning line.
