Abstract:
A display panel including a substrate; a driving transistor on the substrate; a first passivation layer covering the driving transistor; a touch line formed on the first passivation layer; a second passivation layer covering the touch line; an anode electrode formed on the second passivation layer and electrically connected to the driving transistor through a contact hole in the first passivation layer and the second passivation layer; a touch electrode formed on the second passivation layer at a position spaced apart from the anode electrode and electrically connected to the touch line through a touch contact hole of the second passivation layer; a bank covering the anode electrode and the touch electrode and having an opening corresponding to an emission area; and a light emitting layer and a cathode electrode sequentially formed on the anode electrode in the emission area.
