Abstract

The invention provides a display panel and a preparation method thereof. The display panel comprises an array substrate, a light-emitting layer, a first barrier layer, a color film layer, a flat layerand a second barrier layer. The array substrate is provided with a pixel definition layer. The pixel definition layer comprises a plurality of pixel definition areas and retaining walls arranged among the pixel definition areas. The light-emitting layer is arranged in the plurality of pixel definition areas. The first barrier layer covers the array substrate, the pixel definition layer and the light-emitting layer. A plurality of grooves are formed in the first barrier layer. The color film layer is arranged in the grooves. The flat layer covers the first barrier layer and the color film layer. The second barrier layer is arranged on the flat layer. According to the display panel provided by the invention, the first barrier layer is arranged on the light-emitting layer, so that the performance of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display panels, in particular to a display panel and a preparation method thereof. Background technique [0002] At present, in the preparation of display panels, in the preparation process of the light-emitting layer of the display panel, multi-channel precision mask process and high-precision alignment process of inductively coupled devices are required, which makes the process complicated, low yield rate, and high production cost. , and a polarizer needs to be pasted, resulting in light damage, thereby affecting the performance of the display panel, and the manufacturing cost is high. Contents of the invention [0003] The present application provides a display panel and a manufacturing method thereof, so as to improve the performance of the display panel, improve the manufacturing efficiency of the display panel, and reduce the production cost. [0004] The application provides a display panel, inc...
