Problems solved by technology

However, due to the limitations of the process conditions, the sealant will have problems such as glue breakage and poor coating, which will cause external impurities and water vapor to enter the display panel, causing blackening and Mura (spots) around the periphery, which will seriously affect the display quality.
[0003] Therefore, the relevant technologies of the existing display panels still need to be improved.

Abstract

The present invention provides a display panel, a display device, and a method for manufacturing the display panel. The display panel includes: an array substrate, a color film substrate, a sealant, and a retaining wall. The retaining wall is arranged between the array substrate and the color film. Between the substrates, it is in sealing contact with the array substrate and the color filter substrate, and is located inside the sealant to enclose the display area of ​​the display panel, wherein, between the retaining wall and the sealant The containing space is filled with liquid crystal. The retaining wall of the display panel acts as a secondary seal, and the liquid crystal fills the gap between the retaining wall and the frame sealant, which further acts as a seal. It has excellent airtightness and can prevent the sealant from breaking or poor coating When the external gas and impurities interfere with the inside, the peripheral blackening and Mura phenomenon are caused, and the box thickness is uniform, the stability is strong, the picture quality is good, and the display quality is high.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a display device, and a manufacturing method of the display panel. Background technique [0002] The current display panel is formed by forming a sealant around the surrounding area (refer to the structural diagram figure 1 ) to ensure the airtightness of the display panel and isolate the interference from the outside to the inside of the display panel. However, due to the limitations of the process conditions, the sealant will have problems such as glue breakage and poor coating, which will cause external impurities and water vapor to enter the display panel, causing blackening and Mura (spots) around the periphery, which will seriously affect the display quality. . [0003] Therefore, the related technologies of the existing display panel still need to be improved. Contents of the invention [0004] The present invention aims to solve one of ...
