Abstract
(EN)
A display device capable of reducing uneven brightness is provided. The display device is provided with: a liquid crystal display panel (10); a lens sheet (26); and double-sided tape (30) that is configured so as to be provided with a hard adhesive material (32) on one side of a base material (31), and a soft adhesive material (33) on the other side, and that bonds the liquid crystal display panel (10) and the lens sheet (26) to each other. Furthermore, the hard adhesive material (32) is bonded to the liquid crystal display panel (10), and the soft adhesive material (33) is bonded to the lens sheet (26).
