Problems solved by technology

However, due to the strong reflective properties of metal, when the external light is incident on the OLED display panel, the anode will reflect the external light back, which will affect the display contrast when the OLED is displayed.

Abstract

The invention discloses an organic light-emitting display panel, a manufacturing method thereof and a display device, comprising: a base substrate, a driving circuit layer located on one side of the base substrate, and a passivation layer located on a side of the driving line layer away from the base substrate side, and cover the driving circuit layer, a flat layer, located on the side of the passivation layer away from the driving circuit layer, an organic light emitting diode device, located on the side of the flat layer away from the driving circuit layer, and a reflective layer, located on the side of the passivation layer and the flat layer Between, the surface structure of the reflective layer is consistent with the surface structure of the driving circuit layer on the side away from the base substrate. The reflective layer is placed between the passivation layer and the flat layer, so that the surface has a concave-convex structure consistent with the driving circuit layer, so that the reflective surface of the reflective layer has only diffuse reflection of light, thereby reducing the reflected light of external ambient light Intensity, improve the display contrast, enhance the display effect.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an organic light-emitting display panel, a manufacturing method thereof and a display device. Background technique [0002] The organic light emitting diode (Organic Light Emitting Diode, OLED for short) display panel has the characteristics of fast response speed and thinness and has been applied to fields such as mobile display devices and television devices. Generally, an OLED display panel includes a plurality of OLED light-emitting devices as light-emitting units, and each light-emitting device is composed of an anode, a cathode, and a light-emitting layer disposed therebetween. Since the current OLED is self-luminous, different from the liquid crystal display panel, the OLED display panel does not need to install a polarizer on the light incident side, so the device can be made lighter and thinner. [0003] OLED display panels can be divided into two light-em...
