Abstract

A display device in which a curved area having a curved shape and a straight area having a planar shape are defined includes a display panel including a first curved portion overlapping the curved area and a first straight portion overlapping the straight area, a window disposed on the display panel and including a second curved portion overlapping the curved area and a second straight portion overlapping the straight area, and an adhesive layer disposed between the display panel and the window. The adhesive layer includes a first adhesive layer disposed between the first and second straight portions and couples the first straight portion to the second straight portion, and a second adhesive layer disposed in a first space between the first curved portion and the second curved portion and a second space between the first adhesive layer and the second straight portion.
