Abstract: A display device includes a first sub-pixel, and a second sub-pixel located adjacent to the first sub-pixel. Each of the first and the second sub-pixels may include: a first electrode; a pixel defining layer on the first electrode; a first emission component on the pixel defining layer and configured to emit light; a first intermediate layer on the first emission component; a second emission component on the first intermediate layer and configured to emit light; and a second electrode on the second emission component. A trench may be formed by recessing at least a portion of the pixel defining layer in a boundary area between the first sub-pixel and the second sub-pixel. The first intermediate layer may be interrupted over the trench. The second emission component may completely cover the first intermediate layer over the trench.
