DISPLAY PANEL COMPRISING VIBRATION ACTUATOR

A display panel comprising an image module, a reflective sheet, and a frame, comprises a vibration module which is interposed between the reflective sheet and the frame, wherein the vibration module comprises a main piezoelectric driving body, a vibration plate which is physically coupled to the main piezoelectric driving body, and a support portion for supporting either the main piezoelectric driving body and/or the vibration plate from one fixed point positioned on the inside of an outer circumference of the main piezoelectric driving body, wherein the support portion is supported by the frame so that a free end of the outer circumference of the main piezoelectric driving body and the vibration plate can vibrate with the fixed point at the center.
