In the liquid crystal display device, the common electrode (45) comprises a first common electrode (45a) and a second common electrode (45b). The pixel electrode (60) includes a first trunk portion (61a), a second trunk portion (61b), a plurality of first branch portions (62a) extending in the first direction, a plurality of second branch portions (62b) extending in the second direction, a plurality of third branch portions (62c) extending in the third direction, and a plurality of fourth branch portions (62d) extending in the fourth direction. When a pixel is viewed from a direction perpendicular to a plane of the TFT substrate, the boundary between the first common electrode (45a) and the second common electrode (45b) extends over the first trunk portion (61a) of the pixel electrode (60) in a same direction as the direction of the first trunk portion (61a). |

Device includes first and second substrates with a liquid crystal layer in between. The first substrate includes a signal line, a scanning line, an insulating film, a first electrode to which an image signal is transmitted through the signal line, and a second electrode. The first electrode includes a first toothed comb-shaped part. The second electrode includes a second toothed comb-shaped part and a rod-shaped part connected to the second toothed comb-shaped part, wherein the first toothed comb-shaped part and the second toothed comb-shaped part lie in a plane such that they face each other in a pixel. The second substrate has a third electrode which covers at least a display region. The rod-shaped part is arranged to overlap the signal line and the scanning line in a position closer to the liquid crystal layer than the signal line and the scanning line. The insulating film is placed between the rod-shaped part and each of the lines. |
