Display device and method for producing same

A display device comprising:

• a display panel including
• an element substrate having a first resin substrate, a first underlayer film made of an inorganic film and provided on the first resin substrate, and a plurality of switching elements provided on the first underlayer film;
• and
• a counter substrate having a second resin substrate and a second underlayer film made of an inorganic film and provided on the second resin substrate, and arranged such that a side, of the counter substrate, close to the second underlayer film faces a side, of the element substrate, close to the plurality of switching elements;
• and
• a functional sheet bonded to a surface, of the display panel, close to the counter substrate, wherein
• the display device has
• a curved portion in which the display panel is able to be curved at a predetermined radius of curvature, and
• a pair of flat portions between which the curved portion is interposed and a predetermined angle is formed, and in which the display panel is held flatly, and
• the functional sheet is bonded such that the curved portion is able to be maintained at the predetermined radius of curvature.
