Abstract
An embodiment provides a display device including an insulating layer which is continuous between opposed ends of two adjacent lower electrodes from an upper part of one of the ends to an upper part of the other end, a first organic layer which is disposed over the lower electrodes and the insulating layer, a second organic layer which is disposed over the lower electrodes and the insulating layer with the first organic layer interposed therebetween and includes a light emitting layer, and a second electrode which covers the organic layer. The upper face of the insulating layer includes a recess between the two lower electrodes. The aspect ratio of the recess is 0.5 or more.
