Claim:
1. A liquid crystal display device comprising a TFT substrate, a counter substrate, and a liquid crystal interposed between the TFT substrate and the counter substrate, wherein in the TFT substrate, a pixel is present in a region surrounded by scanning lines extending in a first direction and arranged in a second direction, and by video signal lines extending in the second direction and arranged in the first direction, wherein a counter electrode is formed flat on a first insulating film in the pixel, wherein a second insulating film is formed in the peripheral portion of the counter electrode, wherein a third insulating film is formed so as to cover the counter electrode and the second insulating film, wherein a pixel electrode is formed on the third insulating film, wherein the second insulating film and the third insulating film are present between the pixel electrode and the counter electrode in the peripheral portion of the pixel, wherein only the third insulating film is present between the pixel electrode and the counter electrode in the portion other than the peripheral portion of the pixel, wherein a distance between the pixel electrode and the counter electrode is larger at the peripheral portion of the pixel than a distance at an area other than the peripheral portion, and wherein the pixel electrode is connected to a source electrode of a TFT via a through hole formed in the first insulating film and the third insulating film, and the through hole is not formed in the second insulating film.
