a flexible substrate;
a thin film transistor disposed on the flexible substrate;
an interlayer insulating layer disposed on the flexible substrate;
an organic light emitting diode disposed on the thin film transistor;
an encapsulation layer disposed on the organic light emitting diode;
a touch buffer layer disposed on the encapsulation layer;
a touch sensor layer which is disposed on the encapsulation layer and includes a plurality of touch electrodes;
a dam disposed on the flexible substrate corresponding to the non-display area; and
an auxiliary spacer disposed on the flexible substrate so as to overlap at least a part of an outer circumference of the dam, wherein the auxiliary spacer is disposed on the touch buffer layer which is extended from the display area to at least a part of the non-display area and the dam is disposed on the interlayer insulating layer corresponding to the non-display area.
