    Abstract: An organic light-emitting diode display device includes a pixel electrode, a pixel-defining layer, an organic emission layer, and a counter electrode. The pixel-defining layer includes an opening partially exposing the pixel electrode. The organic emission layer is disposed on the pixel electrode. The organic emission layer is disposed in the opening. The counter electrode is disposed on the organic emission layer. The counter electrode opposes the pixel electrode. The pixel-defining layer includes a first pixel-defining layer and a second pixel-defining layer. The first pixel-defining layer is disposed on the pixel electrode and includes an inorganic material. The second pixel-defining layer is disposed on the first pixel-defining layer and includes an organic material. A sidewall of the first pixel-defining layer that is closest to the opening is aligned with a sidewall of the second pixel-defining layer that is closest to the opening.

    Abstract: A display apparatus is provided. The display apparatus includes a first light source unit comprising a first light source that emits light having a first spectral band and a photo-converter that converts the light having the first spectral band to a first color light. A spectral band of the first color light is different from the first spectral band of the light emitted from the first light source. The display apparatus also includes a second light source unit comprising a second light source that emits light having a second spectral band. The light having the second spectral band corresponds to a second color light, and has a same color as the light having the first spectral band. A spectral band of the second color light is different from the spectral band of the first color light.
