Problems solved by technology

[0004] However, the current ODF process has a key bottleneck of insufficient liquid crystal process operation tolerance (LC margin), that is, the liquid crystal volume offset range that satisfies the low-temperature bubble test conditions is too small. The vacuum gap created between the substrates; when the amount of liquid crystal is inaccurate or the height of the spacer is offset, it is easy to generate air bubbles
[0005] One of the solutions to the above problems is to use softer spacers or reduce the area of ​​the spacers, so that the space between the substrates can be adjusted in the process. However, although this method can increase the LC margin, it will Reduce the pressure resistance, not suitable for mass production

Abstract

A liquid crystal panel consists of the first base plate, the second base plate in parallel to the first, liquid crystal layer between two base plates and composite isolation article between two base plates as the isolation article includes multiple soft bodies and multiple rigid bodies. A method for preparing the liquid crystal panel is also disclosed.

Description

technical field [0001] The invention relates to a liquid crystal panel and a manufacturing method thereof, in particular to a manufacturing method of a liquid crystal panel with special spacers. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) is one of the most common displays at present. FIG. 1 is a schematic cross-sectional view thereof, including a first substrate 12 and a second substrate 14, such as a color filter substrate (CF substrate). Or a thin film transistor substrate (thin film transistor substrate, TFT substrate), which also includes a spacer 18 as a support between the substrates 12 and 14 to fill the liquid crystal 16 . [0003] The one drop fill (ODF) technology has gradually replaced the traditional technology as the main technology for manufacturing liquid crystal panels. 2A-2C are schematic diagrams of the ODF process. In FIG. 2A , firstly coat the sealant 13 around the first substrate 12, then drop liquid crystal 16 on...
