摘要： A flexible display device can include a display area in which a plurality of sub pixels is disposed and a non-display area which encloses the display area, a flexible substrate including a folding area and a non-folding area with a folding axis, a thin film transistor disposed on the flexible substrate, an organic light emitting diode disposed on the thin film transistor, and an encapsulation layer disposed on the organic light emitting diode. Also, a touch buffer layer is disposed on the encapsulation layer, a touch sensor layer which is disposed on the encapsulation layer and includes a plurality of touch electrodes, and a dam is disposed on the flexible substrate corresponding to the non-display area. Further, an auxiliary spacer is disposed on the flexible substrate so as to overlap at least a part of an outer circumference of the dam.
