Abstract: A display device according to an embodiment may include a first substrate including an array of pixels, a second substrate coupled to the first substrate, and a sealing member between the first substrate and the second substrate. The second substrate may include a base substrate including a display area overlapping the array of pixels and a peripheral area around the display area; a first compensation structure in the peripheral area, on the base substrate, at least partially overlapping the sealing member, and including an organic material; a second compensation structure in the peripheral area, on the base substrate, spaced apart from the first compensation structure, at least partially overlapping the sealing member, and including the same material as that of the first compensation structure, and a first capping layer covering the first and second compensation structures and including an inorganic material.

Abstract: A display device may include a first transistor, a second transistor, a first electrode, a second electrode, a first optical filter, and a second optical filter. No intervening transistor may be positioned between the first transistor and the second transistor. The first electrode may be electrically connected to the first transistor. The second electrode may be electrically connected to the second transistor. The first optical filter may overlap the first electrode and may have a first circular perimeter in a plan view of the display device. The second optical filter may overlap the second electrode, may have a polygonal perimeter in the plan view of the display device, and may be spaced from the first optical filter.

Abstract: A display device includes a lower substrate, a pixel defining layer, a light emitting layer, an upper substrate, and a light blocking layer. The pixel defining layer is disposed on the lower substrate and includes a first opening and a second opening spaced apart from the first opening in a first direction. The light emitting layer is disposed in each of the first opening and the second opening. The upper substrate is disposed on the light emitting layer. The light blocking layer is disposed on the upper substrate and includes a third opening partially exposing the first opening and a fourth opening partially exposing the second opening. A first shape in which the first opening is exposed by the third opening and a second shape in which the second opening is exposed by the fourth opening are symmetrical to each other about a line of symmetry in a plan view.

Abstract: A display panel includes an upper display substrate including a first pixel area, a second pixel area, a third pixel area, and a light blocking area surrounding the first, second, and third pixel areas and a lower display substrate including a light emitting element. The upper display substrate includes a base substrate, a first bank overlapping the light blocking area and disposed on the base substrate, a second bank overlapping the light blocking area and disposed on the base substrate, a bridge bank disposed on the base substrate between the first bank and the second bank, and an organic material pattern whose at least a portion is disposed on the bridge bank. The display panel has improved reliability.
