Abstract: A display device in one aspect includes a plurality of sub-pixels having an emission sub-pixel and a repair sub-pixel. The display device further includes a light emitting element disposed in the emission sub-pixel and a transistor disposed in the emission sub-pixel. The display device further includes a first reflective layer disposed between the light emitting element and the transistor in the emission sub-pixel, and electrically connected to the transistor. The display device also includes a second reflective layer disposed in the repair sub-pixel, and a connection layer disposed below the first reflective layer and the second reflective layer to overlap the first reflective layer and the second reflective layer. Therefore, defective sub-pixels can be easily repaired.
