Liquid crystal display device

摘要

A liquid crystal display device includes a TFT substrate, an opposite substrate, and a liquid crystal between the TFT substrate and the opposite substrate. In the TFT substrate, there are formed in the following order, a first pixel electrode and a second pixel electrode, a first scan line and a second scan line which extend in a first direction and are arranged in a second direction, a first insulating film, a first video signal line and a second video signal line which extend in the second direction and are arranged in the first direction, a second insulating film, and a common electrode. The first pixel electrode and the second pixel electrode are formed in an area surrounded by the first scan line, the second scan line, the first video signal line and the second video signal line.
