Embodiments of the present invention provide an organic light-emitting display panel and an organic light-emitting display device, which relate to the field of display technology, and can effectively improve lateral light leakage, thereby effectively improving color mixing. The above-mentioned organic light-emitting display panel includes: a display area; a plurality of sub-pixels are arranged in the display area, and each sub-pixel includes an organic light-emitting element; a plurality of reflective structures arranged on the side of the plurality of sub-pixels facing the light-emitting surface; a flattened surface covering the plurality of reflective structures The film layer, the side of the planarized film layer away from the multiple reflective structures is a flat plane; the color filter layer arranged on the side of the planarized film layer away from the multiple reflective structures; the reflective structure includes an insulating bump, insulating The raised block includes a bottom surface and a side intersecting with the bottom surface, and there is a slope angle between the bottom surface and the side surface, and also includes a first reflective metal layer covering the side surface of the insulating raised block; part of the light emitted by the organic light-emitting element is first reflected by the first reflection structure. Reflected by the reflective metal layer, and then emitted through the color filter layer.
Description
【Technical field】 [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel and an organic light emitting display device. 【Background technique】 [0002] The organic light-emitting panel is provided with a plurality of sub-pixels and a color filter layer corresponding to the sub-pixels one by one. The color filter layer is located on the side of the sub-pixel facing the light-emitting surface of the organic light-emitting display panel, and is used to convert the light emitted by the sub-pixel into Colored light. However, since the angles of the light emitted by the sub-pixels are relatively divergent, part of the light emitted obliquely will be emitted through the color filter layer corresponding to the adjacent sub-pixels, resulting in lateral light leakage and resulting in color mixing. [0003] In the prior art, in order to solve the above problems, the following methods are usually adopted: as fig...
