[0059] Figure 2A-2E It is a schematic cross-sectional flow diagram of the manufacturing method of the liquid crystal display panel according to the first embodiment of the present invention. Please refer to Figure 2A , The manufacturing method of the liquid crystal display panel of the present invention includes the following steps: firstly, a first substrate 110 and a second substrate 120 are provided. In one embodiment, the first substrate 110 may be an active element array substrate (Color filter on array, COA) with a color filter layer, and the second substrate 120 includes a light-transmitting substrate 122 and a light-transmitting The common electrode 124 on the substrate 122 . Certainly, those skilled in the art should know that the first substrate 110 of the present invention is not necessarily a substrate using the COA technology, but a general active element array substrate can be selectively used. In this case, the second substrate 120 is a color filter substra...

Abstract

The invention discloses a method for manufacturing a liquid crystal display panel, which comprises the following steps of: firstly, providing a first substrate and a second substrate; secondly, forming a mixed solution between the first substrate and the second substrate, wherein the mixed solution consists of a plurality of liquid crystal molecules and a plurality of macromolecular monomers; thirdly, forming an electrical field between the first substrate and the second substrate; fourthly, performing a first light irradiation procedure of a partial mixed solution to make part of macromolecular monomers polymerized; and finally, performing a second light irradiation of the mixed solution to make macromolecular monomers polymerized.

Description

technical field [0001] The present invention relates to a liquid crystal display panel and a manufacturing method thereof, and in particular to a liquid crystal display panel capable of reducing dark lines and improving display quality and a manufacturing method thereof. Background technique [0002] The multimedia technology in today's society is quite developed, mostly benefiting from the progress of semiconductor components and display devices. As far as displays are concerned, liquid crystal display panels with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. Generally speaking, a liquid crystal display panel is mainly composed of an active element array substrate, a color filter substrate and a liquid crystal layer between the two substrates. [0003] In order to improve the manufacturing quality of liquid crystal display panels, PSA (Polym...
