Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] OLED display panels have the advantages of self-illumination, high contrast, fast response, low power consumption, wide viewing angle, thin thickness and easy realization of flexible display. OLED display panels generally include: bottom emission OLED display panels and top emission OLED display panels. In a bottom-emitting OLED display panel, light emitted from the organic light-emitting layer exits the anode side of the display panel, and in a top-emitting OLED display panel, light emitted from the organic light-emitting layer exits the cathode side of the display panel.

[0056]Compared with the bottom-emitting OLED display panel, since the light emitted by the top-emitting OLED display panel is emitted from the cathode side,...

Abstract

The invention provides a display panel and a manufacturing method thereof, and a display device belongs to the technical field of display. The display panel includes a reflective electrode layer laminated on a substrate, an organic light emitting layer for reflecting light irradiated on a surface of the reflective electrode layer remote from the substrate, and a transparent electrode layer for transmitting light irradiated on the transparent electrode layer. Wherein the surface of the reflective electrode layer remote from the substrate is in a concave-convex shape. The invention improves thelight emitting efficiency of the display panel. The present invention is used to display images.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] An organic light-emitting diode (English: Organic Light-Emitting Diode; OLED for short) display panel includes an anode, an organic light-emitting layer, and a cathode stacked in sequence. Moreover, compared with the bottom-emission OLED display panel (the light emitted from the organic light-emitting layer is emitted from the anode side of the display panel), the top-emission OLED display panel (the light emitted from the organic light-emitting layer is emitted from the cathode side of the display panel) has a larger The characteristics of high aperture ratio and high display color purity make top-emitting OLED display panels have good development prospects. [0003] In the related art, the surface of the anode of the top emission OLED display panel close to the organic...
