Display panel, display panel preparation method and display device
The invention discloses a display panel, a display panel preparation method and a display device. The display panel comprises a first electrode layer, a pixel definition layer and an organic light-emitting layer, the first electrode layer comprises a plurality of strip-shaped electrodes, and the strip-shaped electrodes extend in the first direction and are arranged at intervals in the second direction; the pixel definition layer comprises a plurality of first dams and a plurality of second dams; the multiple first dams are arranged in an array and arranged between every two adjacent strip-shaped electrodes, and in the first direction, a gap exists between every two adjacent first dams; the second dam is arranged on the first electrode layer, extends in the second direction and is arranged in the interval; the first dams and the second dams enclose a plurality of pixel pits, and the organic light-emitting layers are arranged in the pixel pits; the first dam and the second dam are both made of hydrophobic materials. According to the technical scheme provided by the embodiment of the invention, the PM driving substrate can be used for preparing a device by applying an ink-jet printing method, and ink is effectively prevented from infiltrating the pixel pit wall and overflowing out of the pixel pit.
本发明公开了一种显示面板、显示面板制备方法及显示装置。该显示面板包括：第一电极层、像素定义层和有机发光层；第一电极层包括多个条状电极，各条状电极沿第一方向延伸，在第二方向上间隔排布；像素定义层包括多个第一堤坝和多个第二堤坝；多个第一堤坝呈阵列排布，且设置于相邻两条状电极之间，在第一方向上，相邻两个第一堤坝之间存在间隔；第二堤坝设置于第一电极层上，沿第二方向延伸，且设置于间隔内；第一堤坝与第二堤坝围成多个像素坑，有机发光层设置于像素坑中；其中，第一堤坝和第二堤坝的材料均为疏水性材料。本发明实施例的技术方案使PM驱动基板可应用喷墨打印方法制备器件，有效防止墨水浸润像素坑壁以及溢出至像素坑外。
