Problems solved by technology

However, in actual production, due to the difference in the uniformity or deformation of the spacer size, the gap around the liquid crystal panel is larger than the central area, generally about 0.2 microns (μm), which will cause the liquid crystal panel to turn white or yellow. Adverse consequences, affecting the product yield of LCD panels

Embodiment Construction

[0025] figure 1 It is a schematic diagram of the structure of the liquid crystal panel, such as figure 1 As shown, the liquid crystal panel generally includes an array substrate 2 and a color filter substrate 1 , and the array substrate 2 and the color filter substrate 1 are bonded and connected by a sealant 4 arranged on the edge. A spacer 3 is also provided between the array substrate 2 and the color filter substrate 1 to support the array substrate 2 and the color filter substrate 1 to ensure that a required gap is formed between the array substrate 2 and the color filter substrate 1 (the cell gap). Generally speaking, the spacer 3 is located at the edge region of the array substrate 2 and the color filter substrate 1, so, due to the difference in the uniformity or deformation of the size of the spacer 3, the gap ratio at the periphery of the liquid crystal panel will be greater than that at the central region. The gap is large, which leads to the adverse consequences of ...

Abstract

The invention discloses a liquid crystal display panel and a manufacturing method thereof and a display device. The liquid crystal display panel comprises an array substrate and a color film substrate; the array substrate and the color film substrate are glued through sealing compound; a position for the sealing compound and an extensible structural layer are arranged on the array substrate or the color film substrate. According to the liquid crystal display panel, a gap formed in an edge of the liquid crystal display is matched with a gap formed in a central area due to adjustment of the thickness of the extensible structural layer, accordingly a whitening or yellowing appearance of the liquid crystal panel is eliminated and the product yield of the liquid crystal panel is improved.

Description

technical field [0001] The invention relates to liquid crystal panel processing technology, in particular to a liquid crystal panel, a manufacturing method thereof, and a display device. Background technique [0002] At present, in the production process of the liquid crystal panel, the array substrate and the color filter substrate need to be manufactured separately, and then the edges of the array substrate and the color filter substrate are bonded together by a sealant, and then liquid crystal is filled in the middle of the sealant. In order to maintain the uniformity and pressure resistance of the peripheral gap (gap), spacers need to be added to the sealant. However, in actual production, due to the difference in the uniformity or deformation of the spacer size, the gap around the liquid crystal panel is larger than the central area, generally about 0.2 microns (μm), which will cause the liquid crystal panel to turn white or yellow. Adverse consequences affect the prod...
