An organic light-emitting device and a heterocyclic compound, the device including a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode and including an emission layer, wherein the organic layer includes a heterocyclic compound represented by Formula 1: 

Heterocyclic compound and organic light-emitting device including the same

An organic light-emitting display (OLED) device includes an anode, an organic emitting layer on the anode, and a cathode on the organic emitting layer. The cathode is configured to transmit at least a part of light emitted from the organic emitting layer and is formed of an alloy having a first metal and an oxide of a second metal. The cathode contains an alloy of a metal and a metal oxide and has an increased thickness, such that the process margin for the cathode can be improved.
