Abstract: A display device is disclosed. The display device may include a first pixel and a second pixel. The first pixel may include a first light emitter and a first color converter overlapping the first light emitter. The second pixel may immediate neighbor the first pixel, may include a second light emitter and a second color converter overlapping the second light emitter. When a distance between the first light emitter and the second light emitter is x and a distance between the first light emitter and the first color converter is y, the following equation is satisfied: y=x×tan θ1 wherein θ1 is (90−θ), and the θ is an included angle between a line perpendicular to a light emitting face of the first light emitter at a point of the light emitting face and a line connecting the point of the light emitting face to any point away from the line perpendicular to the light emitting face, the θ has a range of an angle corresponding a luminance ratio value in the range of 1% with respect to the light emitted from the first light emitter to an angle corresponding a luminance ratio value in the range of 15% with respect to the light emitted from the first light emitter.
