Display panel and manufacturing method thereof and display device

Abstract

The invention discloses a display panel and a manufacturing method thereof and a display device. Orthographic projection of a drive circuit in a border area and a graph with periphery wires on an array substrate is not overlapped with orthographic projection of a graph of a black matrix in the array substrate, in other words, no black matrixes are arranged in the area where the drive circuit and the graph with the wires are located; therefore, shielding of the black matrixes on ultraviolet light does not needed to be considered, the area where the drive circuit is located and gap width among the periphery wires can be reduced, the width of the border area is reduced, and narrow border design of the display panel is realized; in addition, a border sealing adhesive contains substances formed after discoloration of thermochromism materials with preset concentration during the curing process, so that the border sealing adhesive itself can achieve the effect of preventing the display panel from light leak after the curing treatment although no black matrixes are arranged in the area, where the drive circuit and the graph with the periphery wires are located, of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method and a display device. Background technique [0002] Today, narrow bezel design has become an important trend in the development of the display field. Because of its beautiful design and low cost, it plays a very central role in large-size splicing design. Therefore, many display device manufacturers are pursuing narrow bezel design. [0003] At present, most display products are Gate Driver on Array (GOA) products, that is, GOA driving circuits for driving gate lines are distributed in the frame areas on the left and right sides of the array substrate of the display panel, and in the frame area There are generally some peripheral traces distributed. [0004] Specifically, the structure of the existing display panel is as figure 1 As shown, it includes an array substrate 1 and a color filter substrate 2, and the array substrate 1 is provi...

Problems solved by technology

However, the display panel with the above structure is provided with a black matrix 4 in the frame area to prevent light leakage from the display panel, so in the design, in order to use ultraviolet light to cure the frame sealant 5 from the side of the array substrate 1, ensure that There is enough light to pass through so that the sealant 5 is completely cured, and a wide gap needs to be set in the area where the GOA drive circuit 3 is located and between the peripheral traces, so that the GOA drive circuit 3 and the peripheral traces as a whole The occupied space becomes wider, which is not conducive to realizing the narrow border of the display panel
