Abstract

The embodiments of the present application disclose an organic light-emitting display panel. It includes: a pixel definition layer, including a plurality of pixel openings; a black matrix layer, including a plurality of first through holes and a light shielding part surrounding the plurality of first through holes; a first organic film layer, at least filled in the first through holes a second through hole is formed in each first through hole; an organic flat layer covers the black matrix layer and the first organic film layer and fills each second through hole; and a color filter layer, set on the organic flat layer. The embodiments of the present application can reduce the light loss inside the display panel and improve the transmittance.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an organic light-emitting display panel and a display device. Background technique [0002] At present, organic light-emitting diode (Organic Light-Emitting Diode, OLED) mobile phone products are developing towards large size, high refresh rate, and high brightness. higher requirements. [0003] Polarizer (POL) can effectively reduce the reflectivity of the panel under strong light, but it loses nearly 58% of the light output. This greatly increases the lifespan burden of OLEDs; on the other hand, the polarizers are thick and brittle, which is not conducive to the development of dynamic bending products. Therefore, how to improve the light-emitting efficiency of OLED devices is the development direction of low power consumption of OLED products in the future. SUMMARY OF THE INVENTION [0004] Embodiments of the present application provide an organic light-emi...
