Abstract
According to one embodiment, a display device includes a first area, a second area, a boundary including a linear first boundary parallel and a curved second boundary and surrounding the first area, and a light-shielding layer including a first light-shielding portion located in the second area. An end portion of the first light-shielding portion on the first area side includes a linear first end portion located on the first boundary, a curved second end portion located on the second boundary in a first round area, and a stepwise third end portion which extends such that the third end portion is bent in a second round area.
