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.

Abstract: A display device includes a plurality of pixels, each including a first sub-pixel indicating a first color, a second sub-pixel indicating a second color, and a third sub-pixel indicating a third color, data lines coupled to pixels arranged in a first direction and configured to supply a data signal to the coupled pixels, gate lines coupled to pixels arranged in a second direction crossing the first direction and configured to supply a gate signal to the coupled pixels, and a compensation circuit configured to calculate a difference between grayscale values of a data signal to be supplied to the first to third sub-pixels, and generate a clock signal based on the difference that controls a start time at which the data signal is inputted to the pixels.
