Claim 0:
1. A display device comprising:
a flexible substrate comprising an active area and a bending area;
a first thin-film transistor disposed in the active area, the first thin-film transistor comprising a polycrystalline semiconductor layer, a first gate electrode, a first source electrode, and a first drain electrode;
a second thin-film transistor disposed in the active area, the second thin-film transistor comprising an oxide semiconductor layer, a second gate electrode, a second source electrode, and a second drain electrode;
a first planarization layer covering the first thin-film transistor and the second thin-film transistor in the active area, the first planarization layer extending to the bending area;
a connection electrode disposed on the first planarization layer;
a second planarization layer disposed on the first planarization layer including the connection electrode in the active area and the bending area; and
a light emitting element disposed on the first planarization layer in the active area, the light emitting element having an anode and a light emitting stack,
wherein the light emitting stack includes at least one light emitting layer.
