Abstract

Provided are a liquid crystal display device, a manufacturing method thereof, and an electronic device. The liquid crystal display device includes: a plurality of scanning lines and a plurality of signal lines disposed on one of paired substrates disposed to face each other with a liquid crystal layer interposed therebetween, the plurality of scanning lines and the plurality of signal lines The lines extend in different directions; and the alignment film, the pixel electrode, the insulating layer and the common electrode are sequentially arranged from one side of the liquid crystal layer, and the alignment film is rubbed in a rubbing direction which has a given direction relative to the direction in which the pixels are arranged. fixed inclination. The pixel electrode is separated by a scan line and a signal line, and has a sub-pixel composed of a first area and a second area. The first region has a plurality of slit-shaped openings having a given inclination in the first direction with respect to the rubbing direction. The second region has a plurality of slit-shaped openings having a given inclination in the second direction with respect to the rubbing direction.

Description

technical field [0001] The present technology relates to a liquid crystal display device, a method of manufacturing the liquid crystal display device, and electronic equipment including the liquid crystal display device. Background technique [0002] An FFS (Fringe Field Switching) type LCD (Liquid Crystal Display) panel is known as an LCD panel of a horizontal electric field. LCD panels of the FFS type have been applied to portable electronic devices such as mobile phones, and such electronic devices are widely used. Portable electronic devices are often used outdoors, and the user of the device may have the opportunity to view the display screen of the portable electronic device through polarized sunglasses. At this time, if the FFS type LCD panel has linear polarization characteristics, and if the transmission axis of polarized sunglasses forms an angle of 0 degrees and 180 degrees or an angle of 90 degrees and 270 degrees with the transmission axis of the FFS type LCD p...
