Display panel, preparation method thereof and display device
The embodiment of the invention provides a display panel, a preparation method thereof and a display device. The display panel comprises a substrate and a pixel definition layer, the pixel definition layer comprises a plurality of first retaining wall parts, a plurality of second retaining wall parts and a third retaining wall part, the first retaining wall parts extend in the first direction and are arranged in the second direction, and the second retaining wall parts extend in the second direction and are arranged in the first direction. The plurality of first retaining wall parts and the plurality of second retaining wall parts intersect with each other to define a plurality of openings, each third retaining wall part is located between every two adjacent second retaining wall parts and located on the side, away from the substrate, of the corresponding first retaining wall part, and the heights of the second retaining wall parts and the third retaining wall parts relative to the substrate are both larger than the heights of the first retaining wall parts relative to the substrate; the size of the third retaining wall part in the first direction is smaller than that of the opening in the first direction. According to the technical scheme, the problem that the film thickness is not uniform during ink-jet printing can be solved.
本公开实施例提供一种显示面板及其制备方法、显示装置。显示面板包括基板以及像素定义层，像素定义层包括多个第一挡墙部、多个第二挡墙部及第三挡墙部，第一挡墙部沿第一方向延伸，第二方向排列，第二挡墙部沿第二方向延伸，第一方向排列，多个第一挡墙部和多个第二挡墙部相互交叉限定出多个开口，第三挡墙部位于相邻的两个第二挡墙部之间并位于第一挡墙部背离基板的一侧，第二挡墙部和第三挡墙部相对基板的高度均大于第一挡墙部相对基板的高度；第三挡墙部在第一方向上的尺寸小于开口在第一方向上的尺寸。本公开的技术方案可以改善喷墨打印时膜厚不均匀的问题。
