Display device and production method for the same

A display device and a production method for the display device having a pixel region formed by arraying a plurality of pixels each having an organic layer held by a lower electrode and an upper electrode on a substrate are provided. The production method for the display device of the invention includes, in one embodiment, a first step of forming a first insulating film on the substrate, a second step of forming a plurality of such lower electrodes each corresponding to each of the pixels on the first insulating film in the pixel region, forming a conductive film on the first insulating film in a peripheral region outside the pixel region, and forming a hole, in the conductive film, which extends to the first insulating film, and a third step of performing a bake treatment on the substrate on which the lower electrode and the conductive film are provided.
