Abstract

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.

Description

technical field [0001] The invention relates to the field of display devices, in particular to an OLED display panel, a preparation method thereof, and a display device. Background technique [0002] Currently common display devices include passive light emitting display devices (such as liquid crystal display devices) and active light emitting display devices (such as OLED (Organic Light Emitting Diode, organic light emitting diode) display devices). Compared with the passive light-emitting display device, it has the advantages of smaller thickness, low power consumption, fast response speed, etc., so the active light-emitting display device has greater market competitiveness. [0003] The OLED display device includes an OLED display panel. The OLED display panel includes a plurality of OLEDs. Each OLED usually includes an anode, an organic light-emitting layer and a cathode. In an OLED display panel, the anode is usually first fabricated on the substrate, and then the An ...
