Abstract: A display device includes first and second electrodes disposed on a substrate, the first and second electrodes extending in a direction and being parallel to each other, a first insulating layer disposed on the first and second electrodes, light-emitting elements disposed on the first insulating layer, the light-emitting elements having first end portions disposed on the first electrode and second end portions disposed on the second electrode, and a partition disposed on the first insulating layer and being parallel to the first electrode, the partition including a first part that overlaps the light-emitting elements, and second parts that do not overlap the light-emitting elements, wherein a vertical distance from a top surface of the first electrode to a top surface of the first part is equal to a vertical distance from the top surface of the first electrode to top surfaces of the second parts.

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.
