Abstract
(EN)
A display device may comprise: a substrate; an organic light emitting element disposed on the substrate; a pixel circuit disposed between the substrate and the organic light emitting element, electrically connected to the organic light emitting element, and including a first transistor and a second transistor; a first metal layer which is disposed between the substrate and the pixel circuit while overlapping the first transistor and to which a first voltage is supplied; and a second metal layer which is disposed between the substrate and the pixel circuit while overlapping the second transistor and to which a second voltage different from the first voltage is supplied.
