Abstract: Provided is an organic light emitting display device. The organic light emitting display device comprises a substrate including an active area and a non-active area enclosing the active area; a first inorganic encapsulation layer disposed in the active area and at least a part of the non-active area on the substrate; an organic encapsulation layer disposed on the first inorganic encapsulation layer; a second inorganic encapsulation layer disposed on the organic encapsulation layer; and a dam disposed between the first inorganic encapsulation layer and the second inorganic encapsulation layer in the non-active area. At least a part of the organic encapsulation layer is in contact with one surface of the dam.

Abstract: Discussed is a flexible display device including a substrate on which sub-pixels are defined, an organic light emitting element disposed on the substrate and disposed to correspond to each sub-pixel of the sub-pixels, an encapsulation layer on the organic light emitting element, a plurality of color filters disposed on the encapsulation layer to correspond to the sub-pixels, respectively, a black matrix disposed between the plurality of color filters, a plurality of spacers positioned between the plurality of color filters and disposed on the black matrix, and an overcoating layer disposed to cover the plurality of color filters, the black matrix, and the plurality of spacers. Each of the plurality of spacers has a first surface closest to the encapsulation layer and a second surface distal from the first surface, and a width of the second surface is greater than a width of the first surface.
