1. A display device, comprising:
a base substrate;
an active element layer including a plurality of active elements, a plurality of display wires, and a drive circuit all of which are provided above the base substrate;
a light-emitting element layer including a plurality of light-emitting elements provided on the active element layer; and
a sealing layer including an organic film provided to cover the light-emitting element layer,
the base substrate, the active element layer, the light-emitting element layer, and the sealing layer constituting a display panel including: a display region displaying an image; a frame region provided to surround the display region; and at least one round corner having a curved outline in plan view,
the display region being provided with the display wires including: a plurality of gate wires extending in parallel with one an other in a first direction; a plurality of emission control wires extending in parallel with the gate wires; and a plurality of source wires extending in a second direction intersecting with the gate wires and the emission control wires, and the light-emitting elements being each included in a pixel circuit provided for each of intersections of the gate wires and the source wires,
the frame region being provided with: the drive circuit including a gate driver configured to output a gate signal to the gate wires, and an emission driver configured to output an emission control signal to the emission control wires; and a barrier wall surrounding the organic film,
the frame region including: a frame corner including the at least one round corner of the display panel; and two sides provided so that the frame corner is sandwiched between the two sides, the two sides including a first frame side in parallel with the gate wires, and a second frame side in parallel with the source wires,
at least one of the gate driver and the emission driver being divided and provided to the first frame side and the second frame side, and
a length between the display region and the barrier wall in at least a portion of the frame corner being shorter than a length between the display region and the barrier layer in the first frame side.
