ABSTRACT:
An OLED display including: a first substrate; an opposing second substrate; an organic light-emitting unit disposed on a side of the first substrate that faces the second substrate; a driving circuit disposed on a side of the second substrate that faces the first substrate and connected to the organic light-emitting unit; and a filter. The organic light-emitting unit includes that is an anode, a cathode, and an organic emission layer disposed therebetween. The organic emission layer includes a blue emission layer a yellow emission layer. The filter is to convert light from the yellow emission layer into red light and green light.
