Manufacturing method for liquid crystal display panel

Abstract

The invention provides a manufacturing method for a liquid crystal display panel. According to the method, while black matrixes are formed, grooves are formed in black matrixes of peripheral areas; or while color blocking layers or spacers are formed, color blocking retaining walls or spacer retaining walls are formed on the black matrixes of the peripheral areas, a gluing area is formed between the grooves and the color blocking retaining walls or spacer retaining walls in a defined mode so as to isolate frame adhesive from a liquid crystal, and therefore the problem that due to contamination of contact between the frame adhesive and the liquid crystal, the peripheral areas of the liquid crystal display panel are uneven in brightness can be eliminated; the manufacturing process is simple, and an additional photomask and an additional exposure manufacturing process are not needed; the color blocking retaining walls or the spacer retaining walls can have an effect of supporting upper and lower substrates, and the production cost is reduced; in addition, as the grooves are formed in the black matrixes of the peripheral areas and filled with the frame adhesive, bonding force between the black matrixes and the upper and lower substrates is increased indirectly, and the stripping phenomenon is avoided; the width of the frame adhesive is adjustable, and therefore diversity requirements of narrow frame design are met.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a liquid crystal panel. Background technique [0002] A thin film transistor liquid crystal display (ThinFilmTransistor-LiquidCrystalDisplay, TFT-LCD) includes a color filter substrate (ColorFilterSubstrate, CFSubstrate,) and a thin film transistor array substrate (ThinFilmTransistorSubstrate, TFTSubstrate), and there are transparent electrodes on the inner side of the substrate. A layer of liquid crystal molecules (LiquidCrystal, LC) is sandwiched between the two substrates. The liquid crystal display controls the orientation of the liquid crystal molecules through the electric field, changes the polarization state of the light, and realizes the purpose of display by using the polarizer to realize the penetration and blocking of the light path. [0003] The CF substrate and the TFT substrate are combined by a sealant. The sealant is generally compose...

Problems solved by technology

Although the material of the support 103 is a relatively low-cost consumable, as the production capacity of each factory continues to increase, the consumption should not be underestimated.

[0006] Finally, due to the current mainstream process conditions, the black matrix (BlackMatrix, BM) 104 will be in direct contact with the glass substrate on the side of the CF substrate 100, and through the analysis of the panels with the upper and lower substrates peeling (peeling) phenomenon, it is known that most of the panels The peeling occurs between the black matrix and the glass substrate, especially with the increase of the panel size and the unreasonable design of some installation modules

The peeling of the upper and lower substrates will bring greater loss to the product, and research has found that the bonding strength between the sealant and the glass substrate is significantly higher than that between the black matrix and the glass substrate
