Abstract
A display device includes a base substrate, a thin film transistor layer including an upper layer insulating film and an organic resin layer, a plurality of light-emitting elements provided on the thin film transistor layer and each including a common function layer, a non-display region provided in the display region, an opening provided in the non-display region and passing through the base substrate, and a first frame-shaped protruding portion provided on the upper layer insulating film in a circumferential shape along the opening. The first frame-shaped protruding portion includes a portion where an area of a transverse section parallel to an upper face of the base substrate decreases from an upper face to a bottom face, the common function layer is also provided in the non-display region, and a slit surrounding the first frame-shaped protruding portion is formed in the common function layer provided in the non-display region.
