A display device includes a display panel including: a first display region; a main display region; first light-emitting elements at the first display region; a connection part at the first display region, and connecting adjacent first light-emitting elements from among the first light-emitting elements to each other; and a light blocking pattern overlapping with the connection part in a plan view. The light blocking pattern includes: a first light blocking pattern spaced from the first light-emitting elements with a first gap between the first light blocking pattern and adjacent ones of the first light-emitting elements, the first light blocking pattern being located at the same layer as that at which at least a portion of each of the first light-emitting elements is located; and a second light blocking pattern under the first light blocking pattern, at least a portion of the second light blocking pattern overlapping with the first gap.
