Abstract: A display panel includes a contact area which includes an upper conductive layer forming first electrodes of the organic EL elements, a lower conductive layer disposed below the upper conductive layer, a middle layer between the upper conductive layer and the lower conductive layer, and an insulating layer between the lower conductive layer and the middle layer. The middle layer includes a first area and a second area which are conductive and electrically connected to the upper conductive layer, and an insulating separating area which separates the first area and the second area. The lower conductive layer includes a first line which is electrically connected to the first area via a first contact hole, and a second line which is electrically connected to the second area via a second contact hole.
