A flexible display device includes a substrate including a non-bending area and a bending area adjacent to the non-bending area, and a crack prevention pattern disposed in the bending area. The bending area includes a first area having a first stress when bending, a second area having a second stress less than the first stress when bending, and a third area having a third stress less than the second stress when bending. The crack prevention pattern includes a plurality of crack prevention lines. The number of the crack prevention lines in the first area is greater than the number of the crack prevention lines in the third area.

Flexible display device and method of manufacturing the same

A display panel includes a base layer, a circuit layer, and a pixel layer. The base layer includes a plurality of light emitting areas, and a plurality of transmitting areas to transmit light incident thereto. The circuit layer includes a plurality of switching devices disposed on the light emitting areas, and a plurality of photosensors disposed on the transmitting areas. The pixel layer includes a light emitting element to emit light based on reception of a current from at least one of the plurality of switching devices. The light emitting element overlaps with one of the plurality of light emitting areas. At least one of the plurality of photosensors is configured to receive a portion of external light reflected from an external object after transmission of the external light through at least one of the plurality of transmitting areas.
