Curved-surface liquid crystal display panel and production method thereof

Abstract

The invention provides a curved-surface liquid crystal display panel and a production method thereof. According to the production method, reaction monomers mixed in a liquid crystal material form a polymer wall at the edge of each corresponding pixel region between a TFT substrate and a CF substrate or the edge of each subpixel region by virtue of a photomask under the irradiation of ultraviolet light; compared with traditional partitions, the polymer walls are uniformly distributed on each pixel, so that the relatively uniform box thickness of a panel can be guaranteed during bending; meanwhile, the shearing stress between the TFT substrate and the CF substrate is effectively dispersed by virtue of the uniformly distributed polymer walls, so that a frame sealant can be protected from being damaged; and besides, compared with a method for forming the partitions by virtue of photoresistance photoetching, the production method has the advantages that the polymer walls are generated by virtue of in-situ reaction in a liquid crystal box, so that the problem that the box thickness is not uniform due to alignment deviation or terrain deviation is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a curved liquid crystal display panel and the curved liquid crystal display panel. Background technique [0002] A liquid crystal display (LiquidCrystalDisplay, LCD) includes a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing, wherein the liquid crystal panel consists of a color filter substrate (ColorFilterSubstrate, CFSubstrate), a thin film transistor array substrate (ThinFilmTransistorArraySubstrate, TFTArraySubstrate), and the liquid crystal layer (LiquidCrystalLayer, LC) sandwiched between the CF substrate and the TFT array substrate and the sealant (Sealant). There are transparent electrodes on the opposite inner sides of the CF substrate and the TFT substrate. The liquid crystal display controls the orientation of the liquid crystal molecules through the electric field, changes the polariza...

Problems solved by technology

[0004] However, in the process of making a curved display, after the curved surface is formed, since the upper and lower substrates are based on the center of the panel, there will be a relative shift (shift) to the left and right sides in the horizontal direction, which will cause the dislocation of the PS, and the PS will move into the TFT array. In the channel on the substrate side or on the high platform, the thickness of the liquid crystal panel box is uneven, resulting in the problem of Mura or light leakage; in addition, when the bending degree of the panel becomes larger and larger, the edge of the panel is sealed due to the compression of the upper and lower substrates A large shear stress is generated at the place, which leads to the fracture of the sealant
