Abstract
A double-sided organic light emitting diode (OLED) display panel is disclosed and includes a plurality of sub-pixels each of which has a top emission region and a bottom emission region. The top emission region has a first anode metal layer, a first OLED device layer, a first cathode metal layer, and an organic barrier layer. The bottom emission region has a second anode metal layer, a second OLED device layer, and a second cathode metal layer. The present invention can reduce an overall thickness of the double-sided OLED display panel.
