WIPO Patent Application WO/2022/188226
Kind Code:
A1
Abstract:
An organic light-emitting display panel, comprising: a pixel defining layer (100) comprising a plurality of pixel openings (131); a black matrix layer (510) comprising a plurality of first through holes (511) and a light shielding portion (512) wrapped around the plurality of first through holes (511); a first organic film layer (520), wherein the first organic film layer at least fills the first through holes (511), and a second through hole (521) is formed in each of the first through holes (511); an organic flat layer (530) covering the black matrix layer (510) and the first organic film layer (520) and filling each second through hole (521); and a color film layer (540) arranged on the organic flat layer (530). A laminated structure of the display panel reduces light loss inside the display panel, thereby improving the transmittance.
