Display panel, manufacturing method thereof and display device

Abstract

The invention relates to a display panel, a manufacturing method thereof and a display device, solving the problems that after the display panel is covered, a blocking structure and an array substrate or an opposite substrate are separated by a certain distance, so that the blocking effect on the dispersion of liquid crystals is limited. The display panel comprises an array substrate and an opposite substrate which are arranged oppositely, liquid crystal and frame sealing glue, and also comprises a blocking structure which is arranged at the non-display region and is positioned between the liquid crystal and the frame sealing glue, wherein the height of the blocking structure is not smaller than the cover thickness of the display panel before the covering, and after the covering, the height of the blocking structure is equal to the cover thickness of the display panel; the blocking structure adopt the plastic material with the elastic recovery rate lower than the preset threshold value. As the material of the blocking structure between the liquid crystal and the frame sealing glue is the plastic material which cannot generate support force for a substrate, so that not only can the influence on the fluctuation of the cover thickness and layer thickness be alleviated, but also the support force for the substrate cannot be generated, the contact between the liquid crystal and the frame sealing glue can be effectively prevented, and the influence on the display region caused by pollution to the liquid crystal due to the frame sealing glue can be alleviated.

Description

technical field [0001] The present invention relates to the field of display panels, in particular to a display panel, a manufacturing method thereof and a display device. Background technique [0002] The liquid crystal display panel is an important part of the liquid crystal display. In the prior art, the array substrate and the opposite substrate are manufactured first; the array substrate and the opposite substrate are box-aligned through a cell alignment process to form a liquid crystal display panel. Among them, a prominent problem of liquid crystal display products is that during the period after the box alignment process and before the light curing process, the sealant will be impacted by the liquid crystal, and the impact of the liquid crystal may break through the sealant, and may also cause damage to the display panel. The pollution of the surrounding liquid crystals will cause afterimages, surrounding mura and other undesirable phenomena. [0003] At present, in...

AI Technical Summary

Problems solved by technology

[0005] The embodiments of the present invention provide a display panel, its manufacturing method and display device, which are used to solve the problem that the blocking structure of the display panel in the prior art is made of the same material as PS, and is completed by one PS process, but due to the thickness of the box and the layer Due to factors such as fluctuations in thickness and the inability to generate support for the array substrate, there is a certain distance between the barrier structure and the array substrate or the opposite substrate during fabrication, and the barrier effect on liquid crystal diffusion is limited.
