1. An organic light emitting diode device comprising:
a substrate;
a distributed Bragg reflector (DBR) on the substrate;
a first subpixel on the DBR comprising a first subpixel electrode connected to the substrate through a first via;
a second subpixel on the DBR comprising a second subpixel electrode connected to the substrate through a second via and a first optical filler layer isolating the first subpixel electrode from the second subpixel electrode, the second subpixel overlapping the first subpixel;
a pixel definition layer insulating the first subpixel electrode from the second subpixel electrode;
a white organic light emitting diode (OLED) stack on top of the first subpixel electrode and the second subpixel electrode; and
a top electrode on top of the white OLED stack.
