Problems solved by technology

If the number of occurrences of singularities and the location of occurrence are scattered, it will cause rough display
In addition, the response of liquid crystal molecules near the singularity is slow, which also causes afterimages, etc.

Abstract

A liquid crystal display device excellent in display characteristics can be provided without complicating the manufacturing process. The liquid crystal display device of the present invention includes a liquid crystal panel, and the liquid crystal panel has: a first substrate and a second substrate; a vertical alignment film arranged on each substrate; a liquid crystal layer with negative dielectric constant anisotropy, and a unit area of ​​the liquid crystal panel Comprising: a first domain in which an azimuth component of a director of a liquid crystal molecule at a central portion in a thickness direction of the liquid crystal layer faces a first direction; and an azimuth component of a director of a liquid crystal molecule at a central portion in a thickness direction of a liquid crystal layer faces a second direction For the second domain, the first direction is not parallel to the second direction, and the twist angle of the liquid crystal molecules in the liquid crystal layer between the first substrate and the second substrate is less than 45 degrees.

Description

Technical field [0001] The present invention relates to a liquid crystal display device. Background technique [0002] In a vertical alignment (VA: Vertical Alignment) mode liquid crystal display device, in order to improve viewing angle characteristics, an alignment division technology (MVA: Multi-domain Vertical Alignment) has been traditionally adopted. MVA technology is a technology that divides a pixel (or sub-pixel) into a plurality of regions, and aligns liquid crystal molecules in different directions for each region. As a result, the viewing angle dependence of each area is averaged as a whole, so the viewing angle can be expanded. [0003] When a longitudinal electric field is applied to the liquid crystal of the VA mode, the liquid crystal molecules are inclined from the normal direction of the substrate surface. At this time, multiple singularities of the orientation vector field of the liquid crystal molecules are generated at random positions. Generally speaking, i...
