Abstract: A display device may include a substrate, pixels, and a crack mitigation structure. The substrate may include a main region, a sub-region, and a bending region. The bending region may be connected between the main region and the sub-region and may include a curved outline section. The pixels may be disposed on the main region. The crack mitigation structure may be disposed on the bending region. A section of the crack mitigation structure may be substantially parallel to the curved outline section.

Abstract: A display device includes: a substrate; a display area including pixels arranged on the substrate; a first area disposed at one side of the display area; a second area including pads arranged on the substrate; a bending area disposed between the first area and the second area; and a fan-out line disposed in the first area, the bending area, and the second area. The fan-out line includes: a plurality of sub-routing lines arranged in the first area and electrically connected to each other; and a plurality of sub-pad lines arranged in the second area and electrically connected to each other. The number of the plurality of sub-routing lines is greater than the number of the plurality of sub-pad lines.

Abstract: A display device includes a substrate on which an active region and a non-active region disposed are defined. The non-active region at least partially surrounds the active region. A light-emitting element is disposed in the active region on the substrate. An encapsulation layer is disposed on the light-emitting element. Block patterns are disposed in the non-active region on the substrate and at least partially surround the active region. The non-active region includes a first non-active region positioned at a first side of the active region and a second non-active region positioned at a second side of the active region. There are more block patterns disposed in the first non-active region than in the second non-active region.
