Abstract
An organic light-emitting diode (OLED) array substrate and a method of manufacturing the same are disclosed. The OLED array substrate includes a substrate, a thin-film transistor layer, an insulating layer, an anode layer, and a pixel defining layer, wherein the pixel defining layer has a first slot and a second slot. A light-emitting layer is formed in the first slot, and a plurality of fillers are provided in the second slot to form a plurality of discontinuous slots in the second slot for forming a plurality of discontinuous cathode layers. When the cathodes on the surface of the pixel defining layer away from the display area are corroded, the function of the cathodes in the display area would not be affected in such a manner that the display effect of the display device would not be affected.
