Problems solved by technology

[0004] The embodiment of the present application provides a display panel and its manufacturing method to solve the problem that the low topography of the GOA transition area of ​​the existing display panel causes the alignment film materials such as polyimide to flow to the GOA transition area and accumulate when the alignment film is made. The problem

Abstract

The invention discloses a display panel and a manufacturing method thereof. A heightening layer is arranged in the GOA transition region of the display panel so that the terrain of the display panel is relatively gentle as a whole, the phenomenon that materials for manufacturing the alignment film, such as polyimide, are accumulated in the GOA transition region during manufacturing of the alignment film is reduced; moreover, the heightening layer adopts a structure comprising a first heightening sub-layer positioned in the non-via-hole sub-region and a second heightening sub-layer positioned in the via-hole sub-region, the material combined with the first heightening sub-layer is the same as that of the color resistance material and integrated forming with the color resistance layer is facilitated; meanwhile, the material of the second heightening sub-layer is the same as that of the spacer so that the second heightening sub-layer and the spacer are integrally formed conveniently, theproblem that color resistance heightening is inconvenient to adopt due to complex terrains in the via hole sub-region is solved, no extra procedure is added on the whole manufacturing process, the process is mature and batch manufacturing is facilitated.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, the row-driven GOA (Gate Driver On Array) technology of the array substrate is made of a thin film transistor (Thin Film Transistor, TFT) liquid crystal display array, and the gate scanning driving circuit is fabricated on the thin film transistor array substrate. Thereby, the driving mode of progressive scanning is realized, which has the advantages of reducing the production cost and realizing the narrow frame design of the panel, and has been widely developed. However, in the existing GOA display panel, since the thickness of the display area is greater than the thickness of the GOA area and the GOA transition area between the GOA area and the display area, it is easy to cause alignment such as polyimide when making an alignment film. ...
