In an IPS mode liquid crystal display device, a counter electrode is formed flat on a first insulating film. A second insulating film is formed in the peripheral portion of the counter electrode. A third insulating film is formed so as to cover the counter electrode and the second insulating film. A pixel electrode is formed on the third insulating film. The second and third insulating films are present between the pixel electrode and the counter electrode in the periphery of the pixel. 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. An electric field between the pixel electrode and the counter electrode is smaller in the periphery of the pixel than in the vicinity of the center of the pixel, to prevent the occurrence of a domain in the periphery of the pixel.
