Problems solved by technology
[0007] However, from the light-emitting surface or the light-incident surface of the liquid crystal display device 1, since the raised structures 113, 123 are located within the boundary of the pixel electrode of the pixel, the raised structures 113, 123 will affect the aperture ratio; The liquid crystal molecules between the structures 113 and 123 are not affected by the electric field and do not fall over. This phenomenon causes singular points (singular points) to exist in each pixel, making the image presented by the liquid crystal display device 1 flawed.

The liquid crystal display comprises a first base plate, a second base plate and a liquid crystal layer, wherein the first base plate comprises at least one pixel unit and at least one first orientation structure, the pixel unit comprises a pixel electrode, the pixel electrode is positioned in the display region, the first orientation structure is positioned outside the display region, the second base plate and the first base plate are arranged in the opposite directions, the liquid crystal layer is arranged between the first base plate and the second base plate, optically active substances are added in the liquid crystal layer, and the first orientation structure makes a part of liquid crystal molecules of the liquid crystal layer be inclined towards the inside or the outside of the pixel unit.
Description
technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device with a wide viewing angle. Background technique [0002] The liquid crystal display device utilizes the property that liquid crystal molecules have different polarization or refraction effects on light in different alignment states to control the amount of light transmitted, thereby enabling the liquid crystal display device to generate images. [0003] Generally speaking, the traditional twisted nematic (TN) liquid crystal display device has a very narrow viewing angle due to the influence of liquid crystal molecular structure and optical properties. In order to solve this problem, users have recently developed other types of liquid crystal display devices with wide viewing angles, such as: Multi-domain Vertical Alignment (MVA) liquid crystal display devices and Patterned Vertical Alignment (Patterned Vertical Alignment, PVA) liquid crystal disp...
