Abstract: An organic light-emitting display device includes a first substrate having sub-pixel areas, each sub-pixel area having a light-emitting area and a non-light-emitting area; thin-film transistors respectively in non-light-emitting areas of the sub-pixel areas; a first planarization layer in the sub-pixel areas while covering the thin-film transistors; organic light-emitting elements on the first planarization layer and in light-emitting areas of the sub-pixel areas; a liquid crystal layer on the organic light-emitting elements and in the sub-pixel areas and in an area between the sub-pixel areas; and a second substrate on the liquid crystal layer. Liquid crystal molecules of the liquid crystal layer in the light-emitting areas are in a hybrid alignment. In the hybrid alignment, an alignment of the liquid crystal molecules gradually changes from a horizontal alignment to a vertical alignment. Liquid crystal molecules of the liquid crystal layer in the non-light-emitting areas are in a tilted alignment.
