Abstract: Embodiments of the present disclosure relate to an organic light emitting display device which directly vibrates an organic light emitting display panel to generate sound, and includes: an organic light emitting display panel including a light emitting layer including an organic light emitting material layer and an encapsulation layer disposed at one side of the light emitting layer; and a sound generating actuator in direct contact with the organic light emitting display panel to vibrate the organic light emitting display panel to generate sound. Especially, the organic light emitting display panel is a bottom emission type device, and thus can prevent generation of a weighted color mixing phenomenon in a wide viewing angle at the time of panel vibration and reduce the thickness or weight of the panel to thereby enhance the sound generation characteristic.
