Abstract: A method of manufacturing a display device includes forming an uncut electrode on a substrate, at least a portion of the uncut electrode being formed in a non-emission area; disposing a first insulating layer to overlap the uncut electrode; removing at least a portion of the first insulating layer in the non-emission area; cutting the at least a portion of the uncut electrode in the non-emission area; disposing light emitting elements including a first light emitting element in an emission area and a second light emitting element in the non-emission area; and disposing a second insulating layer to overlap the emission area and the non-emission area. The second light emitting element is disposed in the non-emission area where the uncut electrode is not disposed. Also provided is a display device manufactured by the method.

Abstract: A display device includes a first pixel including a first light emitting area in which first light emitting elements are arranged, a second pixel including a second light emitting area in which second light emitting elements are arranged, a light blocking pattern disposed on the first and second pixels to overlap a peripheral area of the first and second light emitting areas and including a first opening corresponding to the first light emitting area and a second opening corresponding to the second light emitting area, and a color filter including a first color filter pattern disposed in the first opening and a second color filter pattern disposed in the second opening. The second pixel includes a greater number of second light emitting elements than a number of the first light emitting elements. The second opening has an area smaller than an area of the first opening.
