Display panel, preparation method thereof and display device
The invention provides a display panel and a display device. The display panel comprises a substrate, a pixel defining layer, an anode, a functional layer and a cathode, the pixel defining layer is arranged on the substrate and comprises a plurality of first dams and a plurality of second dams, the first dams are distributed at intervals, the second dams cover the first dams, and openings are formed in the side walls of the second dams; the anodes comprise a first anode and a second anode, the first anode is arranged between the first dam and the second dam and covers the first dam, and the second anode is arranged in the opening; the functional layer is arranged on the surface, away from the substrate, of the second anode; the cathode covers the second dam and the functional layer. According to the display panel, the first dam and the reflective first anode are arranged in the second dam, and after part of light emitted by the photoelectric device enters the second dam, the light can be guided out to the light emitting surface of the photoelectric device through reflection of the first anode, so that the light emitting rate of the photoelectric device is effectively improved, and the brightness of the display panel is improved.
本申请提供一种显示面板及显示装置。显示面板包括基板、像素界定层、阳极、功能层和阴极；像素界定层设在基板上，像素界定层包括多个第一堤坝和多个第二堤坝，多个第一堤坝间隔分布，第二堤坝覆盖第一堤坝，多个第二堤坝的侧壁形成开口；阳极包括第一阳极和第二阳极，第一阳极设在第一堤坝与第二堤坝之间并覆盖第一堤坝，第二阳极设在开口中；功能层设在第二阳极远离基板的表面上；阴极覆盖第二堤坝和功能层。本申请通过在第二堤坝内部设置第一堤坝和反光的第一阳极，当光电器件发射的部分光线进入第二堤坝内部后，可通过第一阳极的反射将光线向光电器件的出光面导出，从而有效提高光电器件的出光率，进而提高了显示面板的亮度。
