Abstract: Provided is a display device including a pixel. The pixel has: a conductive film; an interlayer insulating film over the conductive film; a first electrode over the interlayer insulating film; an insulating film over the first electrode; an organic layer over the first electrode and the insulating film; and a second electrode over the organic layer. The interlayer insulating film has a first opening portion overlapping with the conductive film. The insulating film covers the first opening portion. A first region of the organic layer in contact with the first electrode surrounds the insulating film. An area defined by a periphery of the first region has at least two symmetry axes in a direction parallel to a surface of the substrate.
