Liquid crystal display panel

Abstract

The invention provides a liquid crystal display panel, comprising a first base plate, a second base plate and a frame glue situated between the first base plate and the second base plate; the liquid crystal display panel further comprises a display zone and a non-display zone; the frame glue is located at a non-display zone and arranged around the display zone; the liquid crystal display panel further comprises a first groove, a second groove, a first spacer and a second spacer; a bulge is formed between the groove wall of the first groove and the groove wall of the second groove, wherein the first groove and the second groove are arranged at one side of the first base place closing to the second base plate; the first groove and the second groove are situated between the frame glue and the display zone; the first groove is arranged between the frame glue and the second groove; the first spacer is extended into the first groove from the second base plate; the second spacer is extended from the second base plate to the bulge and contacted with the bulge. The structure forms a frame glue diffusion buffer layer closing to the frame glue side and a liquid crystal diffusion buffer zone closing to the liquid crystal side; thus the risk of penetration of the frame glue in a narrow side frame to the display zone and liquid crystal puncture is reduced.

Description

technical field [0001] The present invention relates to the technical field of display panels, and more particularly, to a liquid crystal display panel. Background technique [0002] Liquid Crystal Display (LCD)—a flat and ultra-thin display device, is favored by engineers for its advantages of no radiation, lightness and power saving, and is widely used in various information, communication, and consumer electronics products . [0003] The structure of the existing liquid crystal display such as figure 1 As shown, it includes: a TFT substrate 101 , a CF substrate 102 , a liquid crystal 103 , and a sealant 104 . The LCD includes a display area 105 and a non-display area 106, and the sealant 104 is located in the non-display 106 area of ​​the LCD to confine the liquid crystal 103 in the box. The sealant 104 is provided with silicon balls 141 for supporting between the two substrates in the non-display area 106 . A spacer 121 is disposed on the CF substrate 102, and the sp...

Problems solved by technology

[0005] In the production process of the narrow-frame liquid crystal display of the prior art, due to the fluctuation of the amount of glue spit and the uneven diffusion speed resistance, there are fluctuations in the edge diffusion of the frame glue. figure 2 The concave-convex structure shown

When the concave-convex edge of the frame glue 104 contacts with the edge of the liquid crystal 103 to form an inter-embedded shape, the diffusion direction and force distribution of the frame glue are different from the liquid crystal diffusion direction and force distribution, which will lead to different degrees of liquid crystal puncture

[0006] In order to improve the liquid crystal puncture problem caused by the diffusion of the sealant, a barrier wall 142 is added in the non-display area of ​​the CF substrate, such as image 3 As shown, due to the presence of a step difference in the position of the retaining wall 142, the retaining wall is not in contact with the TFT substrate. Therefore, in the actual coating process: the inner edge of part of the frame glue can overlap with the retaining wall, and the edge of the frame glue is neat; however, when the partial When the amount of glue spit out is large, the retaining wall cannot stop the diffusion of the edge of the frame glue, causing part of the frame glue to cross the retaining wall
