Title:
ORGANIC LIGHT-EMITTING DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/014973
Kind Code:
A1
Abstract:
Provided are an organic light-emitting display panel and a manufacturing method. The organic light-emitting display panel comprises a substrate (10), and transparent anodes (20), a pixel definition layer (30), organic light-emitting layers (40), and several cathodes (50) having a reflection function, which are located on the substrate (10), wherein the pixel definition layer (30) is provided with several open slots; the anodes (20) are arranged at one end, close to the substrate (10), of the open slots; the organic light-emitting layers (40) are filled in the open slots; and the cathodes (50) are accommodated at one end, away from the substrate (10), of the open slots. With regard to the organic light-emitting display panel, the cathodes (50) having a reflection function are only manufactured in a light-emitting area, and the cathodes (50) having a reflection function are not manufactured in a non-light-emitting area, so that in a bottom light-emitting device, light emitted from a sub-pixel can be effectively prevented from interfering with an adjacent sub-pixel, thus improving the colour purity and ameliorating the colour cast phenomenon.
