Title:
DISPLAY DEVICE, OLED DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/233287
Kind Code:
A1
Abstract:
An OLED display panel and a manufacturing method therefor, and a display device. The OLED display panel comprises: a substrate base (11); multiple first electrodes (12) located on the substrate base (11); a pixel defining frame (13) located on the substrate base (11) and separating the multiple first electrodes (12), the pixel limiting frame (13) being used for defining multiple subpixel regions; multiple organic functional layers (14) located in the subpixel regions and on the pixel defining frame (13), wherein at least one of the organic functional layers (14) has a hollow structure at a position corresponding to the pixel defining frame (13), and the hollow structure at least separates the organic functional layers (14) having electrical conductivity in two adjacent subpixel regions; and a second electrode (15) located on the multiple organic functional layers (14). The present invention can effectively reduce the occurrence of a crosstalk phenomenon, thereby ensuring the display effect of a display panel.
