Abstract:
The present disclosure relates to an OLED display device, including OLED units and a pixel spacer layer having a plurality of opening portions, which are disposed on a substrate. Each OLED unit includes an anode, a light-emitting functional layer and a cathode which are disposed sequentially in a direction away from the substrate. The light-emitting functional layer is disposed in the opening portions. The pixel spacer layer is provided with a via hole. The display device further includes: an auxiliary electrode disposed below the pixel spacer layer, corresponding to a display area, spaced apart from the anode, and connected to the cathode through the via hole in the pixel spacer layer; and a print circuit board disposed at a side of the substrate away from the pixel spacer layer, configured to transmit a signal of the cathode to the auxiliary electrode through an conductive lead.
