Title
(EN) OLED display panel, manufacture method therefor and display device
(ZH) 一种OLED显示面板及其制备方法、显示装置
Abstract
(EN)
The invention discloses an OLED display panel, a manufacture method therefor and a display device and belongs to the field of display devices. The OLED display panel comprises a substrate base plate, a first pixel definition layer arranged on the substrate base plate and a plurality of OLEDs, wherein a plurality of openings arranged in an array manner are placed on the first pixel definition layer, and each opening is correspondingly provided with an OLED; each OLED comprises a first electrode, an illuminating layer and a second electrode; each first electrode is arranged on a bottom part and a side wall of a corresponding opening, the illuminating layer and the second electrode are orderly arranged on the first electrode, the first electrode is used for reflecting light emitted by the OLED, the side wall of the opening is covered with the first electrode of the OLED, and therefore a reflecting face is formed; light emitted by the OLED can be reflected toward a side, far away from the substrate base plate, of the OLED; light rays can be prevented from entering the first pixel definition layer, and therefore luminance and a light traction rate of the display panel can be improved.
