Abstract
A flexible display device including a touch sensor is disclosed. In one aspect, the display device includes a flexible substrate, a light emission layer formed over the flexible substrate, and an encapsulation layer formed over the light emission layer and comprising a plurality of encapsulating thin films and a touch detecting layer configured to detect a touch input. The encapsulating thin films include at least one inorganic film and at least one organic film and the touch detecting layer is interposed between a selected one of the at least one inorganic film and a selected one of the at least one organic film that are adjacent to each other.
