Title:
OLED DISPLAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/095330
Kind Code:
A1
Abstract:
An OLED display substrate and a manufacturing method therefor. The OLED display substrate comprises a substrate (10), a TFT (90) arranged on the substrate (10), a passivation layer (50) arranged on the TFT (90), a flat layer (60) arranged on the passivation layer (50), a connection electrode (80) which is arranged on the flat layer (60) and is in contact with the TFT (90), an anode (70) which is arranged on the flat layer (60) and covers the connection electrode (80), an organic light-emitting layer (71) arranged on the anode (70) and a cathode (72) arranged on the organic light-emitting layer (71), wherein the connection electrode (80) is in contact with the TFT (90) through contact holes (81) penetrating the flat layer (60) and the passivation layer (50); and the anode (70) is electrically connected to the TFT (90) via the connection electrode (80). By means of the present invention, a short circuit between a cathode and an anode on an OLED display substrate can be prevented, and current concentration caused by the short circuit can be avoided, so as to ensure that an OLED emits light normally.
