Abstract: Screen brightness is improved in an IPS type liquid crystal display device.A common electrode having a slit is disposed over a rectangular pixel electrode with an insulating film attached therebetween. The slit has a linear part and a bend part. The bend part is necessary for preventing pressing domain. The transmittance in the bend part is increased by making the thickness of the insulating film below the bend part of the slit to less than the thickness of the insulating film at the linear part of the slit, thereby increasing the transmittance of the entire pixel. Thus, the screen brightness can be improved.

Abstract: To improve the display quality of a display device, the display device includes a display section and a frame section surrounding a periphery of the display section. A substrate in the display device includes a conductor pattern constituting a circuit section and an insulating film serving as an organic film covering the conductor pattern. The insulating film extends to a peripheral edge of the substrate. A slit, which penetrates the insulating film in a thickness direction, is formed in a corner part of the insulating film. The slit is formed at a position not overlapping the circuit section.
