A display device includes: a plurality of pixel-region mask spacers disposed in a pixel region where a plurality of pixels are disposed; a plurality of frame-region mask spacers disposed in a frame region outside the pixel region so as to surround the pixel region; and a common layer disposed on the plurality of pixel-region mask spacers, the common layer being common to the plurality of pixels, wherein the common layer comprises an end that has undulations in a plan view.

Display device, mask, and method for manufacturing display device

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.
