Abstract: A liquid crystal display (LCD) panel is provided. The LCD panel includes a first sub-sealant and a second sub-sealant arranged in a region where a gate driver on array (GOA) circuit is placed. The first sub-sealant is closer to a display region than the second sub-sealant. Material of the first sub-sealant has stronger adhesion than material of the second sub-sealant. The material of the first sub-adhesive has lower water resistance than the material of the second sub-sealant.

Abstract: A black matrix composition, a liquid crystal display panel and a manufacturing method thereof are provided. The black matrix composition is used to form a black matrix layer, and components and percentages by weight of the black matrix composition are: an inorganic filler, and 5% to 10%; an alkali-soluble oligomer, and 5% to 10%; a crosslinking agent, and 5% to 10%; a photopolymerization initiator, and 1%; a thermochromic agent, and 1% to 10%; and a solvent, and 60% to 85%. When the temperature of the black matrix layer is less than 50° C., the black matrix layer is black. When the temperature of the black matrix layer is higher than or equal to 60° C., the black matrix layer is completely transparent.
