Abstract
An organic light emitting diode device includes: a first substrate; a first electrode on the first substrate; an organic light emitting layer on the first electrode; a second electrode on the organic light emitting layer; and a capping layer on the second electrode. The capping layer may include at least one high refractive-index layer and at least two low refractive-index layers having thicknesses different from each other.
