Problems solved by technology

[0006] The invention provides a liquid crystal display panel, which can solve the problem in the prior art that when two substrates are bonded together using sealant and conductive particles, because the particle size of the conductive particles is larger than the size diameter of the spacer, the peripheral area of ​​the panel and the panel The gap in the central area produces a height difference, and what is more, the supporting spacer and the conductive particles are superimposed on the same position between the thin film transistor substrate and the color filter substrate, thus resulting in a gap between the peripheral area and the central area of ​​the liquid crystal display panel. Different gaps lead to display unevenness (Mura) in the surrounding screen when the LCD panel is displaying

Abstract

The invention relates to a liquid crystal display panel and a manufacturing method thereof. The liquid crystal display panel comprises a first substrate, a second substrate, a frame glue and a liquid crystal layer positioned between the first substrate and the second substrate; the peripheral region of the first substrate is provided with a first metal wiring, a dielectric layer covering the first metal wiring and a contact electrode, wherein, the dielectric layer is provided with a contact hole, and the contact electrode covers on the inner surface of the dielectric layer and the contact hole; the second substrate is arranged corresponding to the first substrate; the frame glue is arranged between the peripheral regions of the first substrate and the second substrate, and comprises conducting particles which are arranged in the contact hole and are contacted with the contact electrode, so that the liquid crystal display panel of the invention can avoid Mura phenomenon of the peripheral picture display caused by the condition that the gap of peripheral region is higher than the gap of the central region.

Description

【Technical field】 [0001] The present invention relates to a display panel and a manufacturing method thereof, in particular to a liquid crystal display panel and a manufacturing method thereof, which can avoid display unevenness (Mura )The phenomenon. 【Background technique】 [0002] The liquid crystal display panel is the key component of the liquid crystal display device. Its main components usually include two glass substrates, a sealant coated between the two glass substrates, and a space formed by the sealant and the two glass substrates. of liquid crystal molecules. Among the above two glass substrates, one of the substrates has multiple sets of pixel electrodes, which are used to control the rotation angle of liquid crystal molecules according to the input data voltage; the other substrate has color filters, which are used to make the liquid crystal panel display color images . In the prior art, the thin-film transistor substrate and the color filter substrate of th...
