21. A rear chassis in a display device, comprising:
-
a non-metallic vibration plate comprising leather, an artificial leather, or a polyetherimide (PEI) film; a protruding portion having a first sub protruding portion protruded in a rear direction, and a second sub protruding portion protruded from a bottom surface of the first sub protruding portion; and at least one acoustic element disposed on the vibration plate, wherein the at least one acoustic element includes; a first electrode including a first electrode pad; a vibration material layer; and a second electrode, wherein the vibration material layer is disposed between the first electrode and the second electrode, wherein the first electrode pad is disposed on a same surface of the vibration material layer as the second electrode, wherein the first electrode pad is spaced apart from the second electrode, wherein the first electrode pad is electrically connected to the first electrode through a conductive material disposed on a side surface of the vibration material layer.
