Abstract: A mask assembly includes a mask and a blocking stick. The mask includes a pattern region formed therein with openings and extends in a first direction. The blocking stick is disposed under the mask and overlaps a first side portion of the mask. The mask further includes dummy opening regions and opening regions. The dummy opening regions are arranged in the first direction in the first side portion of the mask, and are formed therein with openings. The opening regions are arranged in the first direction in a second side portion which is opposite to the first side portion of the mask and correspond to the dummy opening regions, respectively. The number of the openings per a unit area in each of the dummy opening region and the opening region is smaller than the number of the openings per a unit area in the pattern region.

Abstract: A display panel includes: a plurality of first display regions arranged along a first direction; a second display region between the first display regions; a first pixel in each of the first display regions; and a second pixel in the second display region. Each of the first pixel and the second pixel includes: a first color emission element; a second color emission element spaced apart from the first color emission element in the first direction; and a third color emission element spaced apart from the first color emission element in the first direction and from the second color emission element in a second direction. The second direction crosses the first direction. A shape of an emission region of the second color emission element in the first pixel is different from a shape of an emission region of the second color emission element in the second pixel.

Abstract: A display panel includes first display regions, and a second display region between the two first display regions. Each of the first display regions includes first pixels. The second display region includes second pixels disposed in a second direction intersecting a first direction. Each of the second pixels include a first color light-emitting element, a second color light-emitting element, and a third color light-emitting element which are disposed in the first direction. An arrangement of the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element of each of the first pixels may be different from an arrangement of the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element of each of the second pixels.
