1. A display device, comprising:
a substrate;
an organic light-emitting diode disposed on the substrate;
a first layer disposed on the organic light-emitting diode and having a refractive index in a range from about 1.3 to about 1.4;
a second layer disposed on the first layer and comprising lithium fluoride (LiF);
at least one inorganic layer disposed on the second layer; and
at least one organic layer disposed alternately with the at least one inorganic layer,
wherein a refractive index difference between the at least one inorganic layer and the at least one organic layer is about 0.06 or less.
