An organic light emitting display device includes a first substrate having a plurality of organic light emitting structures thereon, a second substrate facing the first substrate to encapsulate the organic light emitting structures, an aperture under a lower surface of the first substrate, and an aperture controller under the lower surface of the first substrate. The organic light emitting structures define a pixel area. The second substrate has a light absorption area. The aperture corresponds to the light absorption area. The aperture controller is adjacent to the aperture.
