Problems solved by technology

[0004] The invention provides a frame sealant and a liquid crystal display device, which can avoid the problem of the metal line width blocking the ultraviolet light by the frame sealant after being cured by ultraviolet light, so as to solve the existing frame sealant and liquid crystal display device. If the metal traces are too dense, it may cause the frame sealant to be cured by ultraviolet light near the array substrate side, resulting in incomplete curing of the frame sealant, which further leads to the technical problem of uneven thickness around the liquid crystal display device.

Embodiment Construction

[0024] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0025] The present invention is aimed at the existing frame sealant and liquid crystal display device. Because the metal wiring around the array substrate is too dense, the frame sealant may be cured by ultraviolet light near the array substrate side, resulting in incomplete curing of the frame sealant. , which further leads to the technical problem of uneven cell thic...

Abstract

The invention discloses a sealant and a liquid crystal display panel. The sealant is prepared from, by mass, 15-40% of epoxy resin, 15-40% of acrylic-based resin, 0.5-2% of a photoinitiator, 5-15% ofa thermal initiator, 1-10% of an ultraviolet photochromic agent and 0-40% of an inorganic filler. The liquid crystal display device comprises a color film substrate, an array substrate and a liquid crystal layer, and the sealant is further arranged at the two ends of the edge between the color film substrate and the array substrate. The sealant contains the ultraviolet photochromic material, whenthe sealant is not irradiated by ultraviolet light close to the color film substrate side, the sealant is colorless or yellow, and when the sealant is irradiated by the ultraviolet light close to thecolor film substrate side, the sealant is black.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a frame sealant and a liquid crystal display device. Background technique [0002] At present, in the production of thin film transistor liquid crystal display (TFT-LCD), liquid crystal and frame sealant need to be dripped on the array substrate or color film substrate, and then the two substrates are combined and bonded in a vacuum environment, and then the frame sealant After curing, the frame sealant is used to bond the array substrate and the color filter substrate, and protect the liquid crystal in the middle from the influence of external air and water. The curing process of the existing PSVA-LCD panel (polymer stabilized vertical alignment liquid crystal display panel) sealant is mainly divided into two steps: first, it is cured by ultraviolet light, and then it is further fully cured by heating. As people's requirements for flat-panel displays increase, narrow-frame dis...
