Abstract: An organic light emitting display device according to an exemplary embodiment of the present disclosure includes a flexible substrate, a polarization layer, an adhesive layer, and a micro coating layer. The flexible substrate includes a display area in which a display unit is disposed, a first non-display area which encloses the display area, a bending area extending from the first non-display area, and a second non-display area extending from one side of the bending area. The polarization layer is disposed on the display unit. The adhesive layer is disposed on at least one of a lower surface and an upper surface of the polarization layer. The micro coating layer is disposed to cover a plurality of wiring lines on the bending area. In this case, at least a part of the side of the adhesive layer adjacent to the bending area is located inside more than a side of the polarization layer adjacent to the bending area. In the organic light emitting display device according to an exemplary embodiment of the present disclosure, the side of the adhesive layer adjacent to the bending area is located more than the side of the polarization layer adjacent to the bending area or a side of the adhesive layer forms a concavely recessed concave portion to form a receiving portion which receives the micro coating layer.
