Abstract
The present disclosure relates to an organic light-emitting diode (OLED) display, and more particularly, to an OLED display having improved light extraction efficiency. According to the present disclosure, since a plurality of holes are formed in a first electrode of a light-emitting diode and a insulating material is disposed in each of the holes, an organic light-emitting layer and a second electrode constitute a microlens, thereby improving light extraction efficiency of the OLED display. As a result, brightness may be improved, and power consumption may be reduced. In particular, since the plurality of holes are formed in the first electrode and the insulating material is disposed in each of the plurality of holes, an interface between the insulating material and the first electrode is decreased, thereby further improving light extraction efficiency.
