摘要:
A display device having an improved light-extraction efficiency and a reduced color sense variation according to a viewing angle includes a pixel electrode on a substrate, an insulating layer defining an emission area via an opening that covers edges of the pixel electrode and exposes a center portion of the pixel electrode, a first light extraction pattern on the pixel electrode, the first light extraction pattern having a side surface inclined at a first angle, and a second light extraction pattern surrounding the first light extraction pattern on an outer portion of the first light extraction pattern, the second light extraction pattern having a side surface inclined at a second angle that is less than the first angle.
