Organic light emitting display device including a sound generating apparatus

An organic light emitting display device, comprising:

• an organic light emitting display panel including a light emitting layer and an encapsulation layer disposed at one side of the light emitting layer, the light emitting layer including a substrate, a plurality of thin film transistors arranged on the substrate, and an organic light emitting material layer between two electrode layers disposed at one side of the thin film transistors;
• and
• a sound generating actuator connected to a surface of the organic light emitting display panel and configured to vibrate the organic light emitting display panel to generate sound,
• wherein the organic light emitting display panel is a bottom emission type organic light emitting display panel,
• wherein an air gap is provided between the organic light emitting display panel and a support structure,
• wherein the support structure comprises a support hole accommodating the sound generating actuator, and
• wherein the sound generating actuator comprises:
• a plate inserted in the support hole;
• a magnet disposed on the plate;
• a center pole disposed at a center of the plate;
• a bobbin disposed to surround the center pole and be connected to the display panel;
• and
• a coil wound around the bobbin.
