Problems solved by technology

For example, in the case of displaying a human face, there are problems that even if there is no sense of incongruity in the expression of the human face when viewed from the front, the overall appearance is whitish when viewed from an oblique direction, and the skin color is slightly gray. The degree level performance turns white and does not look good

Embodiment approach 1

[0068] image 3 is a plan view showing the structure of the pixel electrode 60 of the liquid crystal display device 100 according to Embodiment 1 of the present invention, Figure 4 is for pixel 50 image 3Cross-sectional view of the structure of the A-A' section. In addition, in the description of all the embodiments of the present invention, the extension direction of the scanning line 14 ( image 3 The left and right direction) is the X direction, and the extension direction of the signal line 16 ( image 3 The vertical direction in ) is the Y direction, and the direction perpendicular to the substrate surface (including the TFT substrate 10 ) of the liquid crystal display device 100 is the Z direction. Also, in the positive X direction ( image 3 The direction from left to right) is the direction of azimuth 0°, and the azimuth is set counterclockwise. Positive Y direction ( image 3 The direction from bottom to top) is the direction of azimuth angle 90°.

Abstract

Provided is a liquid crystal display device that delivers high luminance and excellent display quality. A common electrode (45) in said liquid crystal display device comprises a first common electrode (45a) and a second common electrode (45b). A pixel electrode (60) contains a first trunk section (61a), a second trunk section (61b), a plurality of first branch sections (62a) extending in a first direction, a plurality of second branch sections (62b) extending in a second direction, a plurality of third branch sections (62c) extending in a third direction, and a plurality of fourth branch sections (62d) extending in a fourth direction. Looking at the pixel from a direction perpendicular to the surface of a TFT substrate (10), the boundary between the first common electrode (45a) and the second common electrode (45b) overlaps, and extends in the same direction as, the first trunk section (61a) of the pixel electrode (60).

Description

technical field [0001] The present invention relates to a liquid crystal display device. Background technique [0002] At present, as liquid crystal display devices with wide viewing angle characteristics, liquid crystal display devices using IPS (In-plane Switching: in-plane switching) mode or FFS (Fringe Field Switching: fringe field switching) mode, which are transverse electric field modes, have been developed. ; and a liquid crystal display device using a VA (Vertical Alignment: Vertical Alignment) mode as a vertical alignment mode, and the like. Among them, the VA mode is adopted in a large number of liquid crystal display devices because it can realize high contrast. [0003] Among the VA-mode liquid crystal display devices, there are: an MVA (Multi-domain Vertical Alignment: Multi-domain Vertical Alignment) mode liquid crystal display device in which a plurality of domains in which alignment directions of liquid crystals are different from each other are formed in o...
