A display device includes: an element substrate on which light-emitting elements are arranged, the light-emitting elements being arranged in a display region of the element substrate; a sealing resin layer located over the light-emitting elements arranged on the element substrate; and an opposite substrate located opposite the element substrate with the sealing resin layer therebetween. The sealing resin layer includes: a first sealing portion formed along an outer periphery of the display region so as to have a frame-like shape; a second sealing portion formed so as to cover the display region within the first sealing portion; and a dendritic portion being a branched extension of the second sealing portion that extends into the first sealing portion. A tip of the dendritic portion is located within an outer periphery of the first sealing portion.
