1. An organic light emitting diode, comprising:
a substrate;
an anode on the substrate;
a bank on the anode, the bank exposing a part of the anode to define an emission area;
an organic light emitting layer on the emission area and the bank;
a cathode on the organic light emitting layer;
a plurality of light shielding patterns configured to absorb light incident on the plurality of light shielding patterns, the plurality of light shielding patterns on the cathode and overlapping the bank but non-overlapping with the emission area; and
a light loss inducing layer configured to reduce emission of reflected external light, the light loss inducing layer overlapping the emission area and on a same plane as the plurality of light shielding patterns such that the light loss inducing layer is disposed between a pair of light shielding patterns from the plurality of light shielding patterns, the light loss inducing layer having a same thickness as a thickness of the plurality of light shielding patterns.
