Abstract

The invention relates to the field of display, and in particular to a display panel which comprises a first substrate, a second substrate, a sealing frame adhesive layer, wherein the first substrate and the second substrate are arranged in a pairing box manner; the sealing frame adhesive layer is used for sealing the first substrate and the second substrate; black matrix graphs are arranged on the first substrate and the second substrate; opening grooves are formed in black matrix graphs; the sealing frame adhesive layer comprises a transparent and insulated first sealing frame adhesive layer and a second sealing frame adhesive layer surrounding the first sealing frame adhesive layer; the opening grooves of the black matrix graphs can be completely covered by the second sealing frame adhesive layer. The inner layer of the display panel is a common frame sealing adhesive layer of which the periphery is wrapped by the non-transparent sealing frame adhesive layer, and an inner-layer insulating sealing frame adhesive layer has a protection function on a substrate circuit. The opening grooves of the black matrix graphs are completely shielded by an outer-layer non-transparent sealing frame adhesive layer, so that light leakage in the positions of the black matrix graphs can be avoided.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a preparation method thereof. Background technique [0002] In the field of flat panel display, thin film transistor liquid crystal display has gradually become the mainstream product in the field of flat panel display due to its advantages of light weight, thinness, no radiation, and low power consumption. The display panel is the main component of the monitor. The display panel is generally composed of two substrates arranged in a box, and the two substrates are connected and sealed by a sealant. [0003] Since static electricity enters the display panel, it is easy to cause the display panel to turn green and purple, affecting the display effect, and it is also easy to cause the internal wiring to be burned and broken. Therefore, in order to prevent these problems, the method of slotting the black matrix is ​​generally used at present. However, due to the chamfering o...
