This present invention relates to a process of liquid crystal panel with one drop fill (ODF). A black matrix, which can not be penetrated by an ultraviolet light while curing a sealant, is formed on the other substrate. Hence, in this present invention, it can avoid the aforementioned problem during the curing process and simplifies the curing process.

Process and structure of liquid crystal panel with one drop fill

A one drop fill (ODF) liquid crystal display panel has a CF substrate, a TFT substrate, and a liquid crystal layer positioned between the CF substrate and the TFT substrate. The TFT substrate further has a pixel array region positioned in the center part of the TFT substrate, a sealant region position in the periphery region of the TFT substrate, a light-shielding pattern positioned on the sealant region, and a sealant pattern positioned corresponding to the sealant region between the CF substrate and the TFT substrate for assembling the two substrates.

One drop fill LCD panel having light-shielding pattern with first and second metal patterns

The present invention provides a liquid crystal panel with an isolation wall structure and its producing method. The method comprise: selecting one substrate from two substrates that have been put under alignment process and forming on it a plurality of closing isolation wall structure that is mutual-repulsive to liquid crystal; then forming a close sealant on the substrate, the sealant being located between outer edge of the substrate and the isolation wall structure; and then, combining the two substrates for confining liquid crystal in the isolation wall structure and isolating the liquid crystal from the sealant.

Liquid crystal panel with isolation wall structure and its producing method

A structure of liquid crystal display and manufacture method thereof are described. The liquid crystal display is manufactured by a one drop fill process. The display comprises a first substrate, a second substrate, a conductive pattern layer, a black matrix layer, a liquid crystal layer and an ultraviolet-type seal. The metal pattern layer is made of indium tin oxide and formed on the first substrate. Therefore, the metal pattern layer is a transparent layer allowing the ultraviolet light to pass through. The ultraviolet-type seal is pre-cured by the ultraviolet light from the first substrate direction to the seal, and then cured by a heating process. Hence, the liquid crystal pollution problem is reduced.

Structure of LCD manufactured by one-drop fill technology including a substrate with transparent conductive patterns

A liquid crystal display with separating wall is described. The liquid crystal display is manufactured by a one drop fill process. The display comprises a first substrate, a second substrate, a liquid crystal layer and a seal. The separating wall is formed on the first substrate and around a periphery of the first substrate in a non-display area to block efficiently the liquid crystal from spilling out. The height of the separating wall is close to a cell gap, and therefore the separating wall can utilize a technology of spacer on color filter to produce and adjust height thereof. Hence, the quality of liquid crystal displays can be improved and manufacture cost can be reduced.
