In a display panel (1) performing sound generation/sound pickup through vibration, total thickness of a pair of transparent substrates (104, 105) constituting its base is set suitably for a predetermined sound quality required as an acoustic device. Consequently, a card-type device for generating sound and/or picking up sound by vibrating the display panel itself and ensuring a desired sound quality without sacrificing the setup as a display is realized. |
