Liquid crystal display panel and liquid crystal display device

Abstract

The invention belongs to the field of liquid crystal display and particularly relates to a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises a glass substrate, wherein a polyimide (PI) layer is paved on the glass substrate, and densely-distributed and mutually-independent retaining wall sections are arranged at the tail end of the PI layer. According to the invention, the densely-distributed and mutually-independent retaining wall sections are arranged to ensure that the tail end distance of the PI liquid is controlled and the distance from the PI tail end to frame glue can also be reduced during frame glue liquid coating; and as the distance from a visible area to the PI tail end and the distance from the PI tail end to the frame glue are reduced, the narrow-bezel design can be realized.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and more specifically relates to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] Liquid crystal displays have been widely used in recent years due to their advantages of low power consumption, low production cost and no radiation. Among them, the liquid crystal display panel mainly includes a color filter glass substrate and an array glass substrate arranged in a box, and between the two substrates the liquid crystal layer in between. Such as figure 1 As shown, a layer of transparent conductive glass is coated on the color filter glass substrate 1, that is, an ITO layer 4 (Indium Tin Oxide, Indium Tin Oxide, referred to as ITO), and then a layer of PI layer 3 (polyimide) is set on the ITO layer. amine), the PI layer 3 is used for the alignment of the liquid crystals, and provides an initial angle to the liquid crystal molecules, and the arr...

Problems solved by technology

The frame glue is used to support and adhere between the upper and lower substrates. The width D3 of the frame glue generally has no compression space. If the frame glue covers the PI layer, the area of ​​the frame glue adhering to the glass will decrease, which will affect the adhesion and cause glass stability. The risk of poor performance, so that the distance D2 from the end of the PI layer to the sealant cannot be further reduced

Due to the limitation of the above-mentioned traditional process, the distance from the visible area to the edge of the glass substrate cannot be further compressed, so that a narrower frame design cannot be realized
