摘要： A display apparatus includes a substrate, a pixel electrode disposed on the substrate, a first bank including a bank opening exposing a central portion of the pixel electrode, a second bank disposed on an outer side of the first bank and including a greater thickness than the first bank, an emission layer disposed in the bank opening and corresponding to the pixel electrode, an opposite electrode overlapping the first bank, the second bank, and the emission layer, wherein the first bank and the second bank each include a negative-type photoresist.

摘要： 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.-
