OLED显示基板及制备方法、显示面板及显示装置
摘要：
本发明实施例公开了一种有机发光二极管OLED显示基板及制备方法、显示面板及显示装置，包括基板和设置在所述基板上的像素限定层，所述像素限定层上具有限定有机发光元件的发光区域的开口，所述像素限定层具有至少两种厚度，两个相邻且颜色不同的所述有机发光元件所在的开口的高度不同，能够提升PPI，避免混色风险。
摘要（英）：

The invention discloses an organic light-emitting diode OLED display substrate and a manufacturing method thereof, a display panel and a display device. A substrate and pixel limitation layers arranged on the substrate are included. Each pixel limitation layer has an opening limiting the light emitting area of an organic light emitting component. The pixel limitation layers have at least two thicknesses, and the heights of the openings where the two adjacent organic light emitting components with different colors are located are different. PPI can be increased and the risk of color mixing is avoided.
