Abstract
A self light-emitting display device includes a substrate having a circuit board and a color filter pattern on the circuit board. The circuit board includes a driving thin-film transistor. The display device further includes a passivation film above the substrate, a color conversion pattern above the passivation film and overlapping the color filter pattern, and a light-emitting layer above the passivation film and the color conversion pattern. The light emitting layer includes a flat part and a convex part. The convex part is above the color conversion pattern and protrudes convexly relative to the flat part.
