Abstract: An organic light-emitting diode (OLED) display is disclosed. In one aspect, the display includes a substrate, a plurality of OLEDs provided over the substrate, and a plurality of pixel circuits provided between the substrate and the OLEDs. Each of the pixel circuits comprises a plurality of transistors each including an active pattern electrically connected to the respective OLEDs. A shield layer overlaps the pixel circuits and the active patterns of the transistors in the depth dimension of the OLED display.
