Abstract
A display device includes a first pixel electrode, a bank layer defining a first opening exposing at least a portion of the first pixel electrode, a first intermediate layer arranged on the first pixel electrode in the first opening and which emits light including light of a first wavelength, an opposite electrode arranged on the first intermediate layer and including a first region overlapping the first intermediate layer in a plan view, and an upper substrate arranged on the opposite electrode. An optical distance D1 between the first region and the upper substrate satisfies the equation below: D1=A+(λ1)/2×n, where A denotes the minimum optical distance between the first region and the upper substrate at a point where light of λ1 has a maximum intensity, n is an integer equal to or greater than 0, and λ1 denotes the first wavelength.
