HAPTIC DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

According to an embodiment of the present invention, provided is a display device. The display device includes an electro active layer comprising an electro active polymer. In addition, the display device includes an upper electrode and a lower electrode disposed on upper and lower surfaces of the electro active layer. One from the upper surface and lower surface of the electro active layer includes a plurality of concave parts and convex parts. The electro active layer has a buckling structure or a wrinkle structure in the upper portion or lower portion. In addition, the area of the upper surface or the lower surface of the electro active layer is greater than the area when the upper surface or the lower surface is flat. The upper electrode and the lower electrode are disposed to be conformal to the electro active layer.
