A display panel includes a first display substrate, a second display substrate facing and spaced apart from the first display substrate, a non-conductive sealing member disposed between the first display substrate and the second display substrate and formed around an outer perimeter of the display panel, a conductive sealing member disposed inside the non-conductive sealing member when viewed in a plan view, and a connection pad coupled to a side surface of the first display substrate and a side surface of the non-conductive sealing member. A signal line includes an end portion overlapping with the non-conductive sealing member and connected to the connection pad.
