Abstract
A display device includes: a circuit layer; and a light emitting element disposed on the circuit layer. The circuit layer includes: a semiconductor pattern, an insulating layer defining a contact hole therein to expose a portion of the semiconductor pattern, a connecting electrode disposed on the insulating layer and partially disposed in the contact hole, and an auxiliary electrode at least partially disposed in the contact hole and contacting with the connecting electrode and the semiconductor pattern. The connecting electrode does not overlap a portion of the contact hole in a plan view.
