Organic light emitting display

摘要

An organic light emitting display includes an anode (61); an organic layer (63) on the anode (61); and a cathode (62) on the organic layer (63). The cathode (62) includes a first region (62a) and a second region (62b) which are sequentially disposed on the organic layer (63) in parallel. The first and second regions (62a, b) are formed by doping a metal oxide on an indium oxide matrix. The doping density of the metal oxide of the first region (62a) is greater than that of the second region (62b), the metal oxide of the first region (62a) has a density gradient, and the density of the metal oxide in a boundary surface of the first and second regions is the same. An organic light emitting display according to the present invention can increase light emitting efficiency without using a resonance structure.
