A display device includes an insulation substrate on which TFT elements, first electrodes, light emitting layers and a second electrode are stacked in this order. Auxiliary lines are arranged between the insulation substrate and the second electrodes, and an insulation layer is interposed between the auxiliary lines and the second electrode. The auxiliary lines and the second electrode are connected with each other via contact holes formed in the insulation layer. Due to such a constitution, it is possible to enhance image quality of an organic EL display device.
