    Abstract: A display device is disclosed. In one aspect, the display device includes a flexible substrate including a first region, a second region separated from the first region, and a bending region positioned between the first and second regions. The bending region is configured to be bent so as to have a plurality of different curvatures depending on degrees of bending of the flexible substrate. The display device also includes a first display unit positioned in the first region, a second display unit separated from the first display unit and positioned in the second region and an encapsulation layer positioned over the flexible substrate with the first and second display units interposed therebetween. The encapsulation layer directly contacts the bending region of the flexible substrate.
