Abstract

The embodiment of the invention provides an organic light-emitting display panel and a manufacturing method thereof and an organic light-emitting display device, and relates to the technical field ofdisplay. The panel comprises a light-emitting device layer arranged on a substrate, and the panel comprises: a first electrode; a pixel definition layer which is located on the side, back on to the substrate, of the first electrode, wherein the pixel definition layer is provided with a plurality of opening areas, and part of the first electrode is exposed in the opening areas; a retaining wall structure which is positioned in the opening area and is back to one side of the substrate; a light-emitting functional layer arranged at one side, back to the substrate of the pixel definition layer, the opening area and the retaining wall structure; and a second electrode which is positioned on one side, back to the substrate, of the light-emitting functional layer. The retaining wall structure comprises retaining walls, and concave areas are arranged between the retaining walls and the pixel definition layer or between the retaining walls or in the retaining walls. The film thickness of the second electrode at the top of the retaining wall is greater than that of the side wall of the retaining wall and the sunken area. According to the embodiment of the invention, the luminous flux outputby the panel is effectively improved, and meanwhile, the square resistance of the cathode film layer can be prevented from being greatly increased.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel, a manufacturing method thereof, and an organic light emitting display device. 【Background technique】 [0002] With the development of organic light emitting diode (Organic Light Emitting Diode, OLED) display technology and the expansion of large-scale manufacturing industry, OLED display has become the mainstream of mobile display, occupying a considerable market share of medium-sized or even large-sized display screens. [0003] However, when OLED display technology gradually penetrates into some special display application fields, such as augmented reality (Augment Reality, AR) and virtual reality (Virtual Reality, VR) display fields, the constraints of the original device structure on the display performance gradually become revealed. Take the microdisplay in AR and VR glasses as an example. This type of microdisplay needs t...
