Liquid crystal display device panel and manufacturing method thereof

Abstract

The invention provides an MVA (Multi-domain Vertical Alignment)-mode liquid crystal display device panel and a manufacturing method thereof. The panel comprises a first substrate, a second substrate, an organic membrane layer and a liquid crystal layer, wherein the first substrate comprises pixel regions defined by data lines and scanning lines on the first substrate; the organic membrane layer is positioned at the side of the first substrate, which faces to the second substrate; the surface of the organic membrane layer, which faces to the second substrate, is provided with an inclined surface; the liquid crystal layer is positioned between the first substrate and the second substrate; when a pressure is not applied, liquid crystal molecules in the liquid crystal layer are arranged to beperpendicular to the surface of the organic membrane layer close to the liquid crystal layer; and in one single pixel region, the ratio of the area of the inclined plane of the organic membrane layerto the single pixel area is more than 50 percent. In the invention, by regulating the thickness of the organic membrane layer and the thickness of a liquid crystal box, average optical retardation values corresponding to R, G and B are effectively optimized so that the wide viewing angle and the good transmissivity of the liquid crystal box are realized.

Description

technical field [0001] The invention relates to the field of liquid crystal manufacturing, in particular to an MVA mode liquid crystal display panel and a manufacturing method thereof. Background technique [0002] Liquid crystal display devices are widely used in handheld information exchange terminals and various display fields because of their low space occupation rate and low energy consumption. The liquid crystal display device controls the alignment direction of liquid crystal molecules when the light from the light source passes through the liquid crystal layer through an electric field, and changes the transmittance to display images. According to different specific principles, the liquid crystal display device has developed from the early TN mode to the current VA mode and IPS mode. [0003] In the vertical alignment (VA) mode, the liquid crystal molecules are vertically arranged in the liquid crystal layer in the liquid crystal cell relying on the surface anchor e...

Problems solved by technology

[0005] In the existing MVA mode liquid crystal display device, in a single pixel area, the ratio of the area of ​​the protrusion / inclined surface on the substrate to the total display area is usually less than 50%, making it difficult to select the cell thickness for the R, G, and B areas in the pixel. for the best transmittance
