A portable display device minimizes protrusions of a light emitting display panel, such as an organic light emitting display panel, and an integrated circuit to allows the thickness thereof to be reduced. The portable display device includes a light emitting display panel, such as an organic light emitting display panel. A metal plate is located on a rear surface of the organic light emitting display panel. A bottom chassis receives another light emitting display panel, such as a liquid crystal display panel and a backlight assembly. A first printed circuit board is located between the organic light emitting display panel and the bottom chassis. At least a part of either the organic light emitting display panel or the metal plate is arranged in opening portions of the bottom chassis and the first printed circuit board.
