Abstract
A display apparatus includes: a display panel; an enclosure enclosing the display panel; a cover member covering a front surface of the display panel; an actuator connected to the cover member and having a function of applying vibration to the cover member; and a viscous body arranged between the display panel and the cover member. The viscous body is bonded to the display panel and the cover member, and, when a periodic stress having a vibration frequency of ½ period per second is applied to the viscous body, a dynamic elastic modulus of the viscous body is equal to or lower than 1×10−3 of Young's modulus of the viscous body.
