Problems solved by technology

[0006] It can be seen from the above that in the same pixel, the orientation of the liquid crystal is divided into more directions, although better viewing angle performance can be obtained, but the darkened area will be greatly increased and the aperture ratio (that is, the ratio of the light-transmitting area) will be greatly increased. )decline

Embodiment Construction

[0050] Although the present invention can be embodied in different forms, the structures shown in the drawings and described below are only preferred embodiments of the present invention, and please understand that the structures disclosed herein are only considered as examples of the present invention. It is not intended to limit the invention to the particular embodiments shown and / or described.

[0051] The liquid crystal display according to the present invention mainly includes a first substrate and a second substrate. The surfaces of the substrates are vertically aligned, for example using a vertical alignment film. A liquid crystal layer with negative dielectric constant anisotropy is sealed between the two substrates. The liquid crystal molecules included in the liquid crystal layer are substantially perpendicular to the main surface of the first substrate when substantially no electric field is applied to the liquid crystal layer.

[0052] In a vertical alignment li...

Abstract

A liquid crystal display is prepared as setting dielectric constant anisotropy liquid crystal layer between two baseboard being positioned vertically, using the first and the second domain regulator to regulate orientation of said layer to let liquid crystal molecules be tilt - positioned for obtaining the first and the second directions in orientation when voltage is exerted, setting each pixel in either of the first or the second domain regulator, setting different domain regulator in all two adjacent pixels.

Description

technical field [0001] The present invention relates to a liquid crystal display, in particular to a vertical alignment type liquid crystal display. Background technique [0002] A vertically aligned (VA) type liquid crystal display is a type (mode) using a negative type liquid crystal material and a vertically aligned film. When there is no voltage supply, the liquid crystal molecules are aligned in a vertical direction and a black display appears. When a preset voltage is supplied, the liquid crystal molecules are aligned in a horizontal direction to produce a white display. Compared with the twisted nematic liquid crystal display, the vertical alignment liquid crystal display can provide higher contrast and faster response speed, and has the characteristic of providing an excellent viewing angle for black and white display. However, the vertical alignment type liquid crystal display still has a key disadvantage of a narrow viewing angle. This poses a problem that the a...
