Problems solved by technology

However, in the actual alignment, it is found that the pretilt angle is offset during the UV2 process, and the offset degree of different positions is inconsistent. During the investigation, it is found that the inconsistent degree of pretilt angle offset is due to the temperature difference of different corresponding positions of the UV2 machine. As a result, the final angles at different positions are inconsistent, causing black-order moiré (mura) in the dark state

Abstract

Embodiments of the present invention disclose a liquid crystal display panel and a manufacturing method thereof. The liquid crystal display panel comprises: a first substrate, wherein a first alignment film is disposed on a surface; a second substrate, wherein the second substrate is disposed opposite to the first substrate, and a second alignment film is disposed on a surface of the second substrate; and a liquid crystal layer, wherein the liquid crystal layer is disposed between the first alignment layer and the second alignment layer, and the liquid crystal layer comprises liquid crystal molecules, a reactive monomer and a photo-curing material. According to the embodiments of the present invention, the photo-curing material is added, and a curing reaction may occur by irradiating UV light of a particular wavelength on photo-curing molecules, to form a solidified layer and a fixed side chain, so that side chain robustness is improved, tilt angle stability is enhanced, and black-level mura generation in a dark state is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] A liquid crystal display (Liquid crystal displays, LCD) is a widely used flat panel display, which mainly realizes picture display by modulating the light field intensity of a backlight source through a liquid crystal switch. In order to achieve a fast response display effect, the pretilt angle is generated in advance. [0003] In traditional technology, the display mode often adopts the vertical alignment (vertical orientation, VA) mode. During the alignment process, a voltage is first applied. The liquid crystal on the surface is poured at a certain angle. Then ultraviolet light triggers the reaction of Reactive mesogen (RM), and polymerizes on the surface of the PI film to form long-chain molecules, so that the liquid crystal near the surface of the PI film forms a certain preti...
