A display device includes a substrate, on the substrate, a light-emitting element including a first electrode, a second electrode, and a light-emitting layer and a charge transfer layer between the first electrode and the second electrode, in which the display device includes a light-emitting region of the light-emitting element and a non-light-emitting region that is a peripheral portion of the light-emitting region, a protruding portion is provided in a layer lower than the charge transfer layer in part of the non-light-emitting region, and the charge transfer layer is formed as a continuous film in a display region including the light-emitting region and the non-light-emitting region on the substrate, and includes a thin film portion, on the protruding portion, being thinner than a portion in the light-emitting region and a portion in the non-light-emitting region other than the protruding portion.
