    Abstract: A display device includes a first electrode and a second electrode that are spaced apart from and facing each other; a light-blocking layer disposed above the first electrode and the second electrode; and at least one light-emitting element disposed between the first electrode and the second electrode. The light-blocking layer includes a light-blocking portion absorbing light and an opening pattern. The light-blocking portion includes an area partially overlapping the first electrode and the second electrode. The at least one opening pattern exposes portions of the first and second electrodes facing each other and at least a portion of an area between the first and second electrodes facing each other. The at least one light-emitting element overlaps the at least one opening pattern.
