Abstract
A display device includes: a display panel; a first sound generating device disposed below the display panel, where the first sound generating device generates a sound by causing the display panel to vibrate; and a second sound generating device disposed below the display panel, where the second generating sound generating device generates a sound by causing the display panel to vibrate. The first sound generating device includes: a first vibrator which vibrates in a first direction, which is a thickness direction of the display panel; and a second vibrator which vibrates in the first direction, and the second sound generating device includes: a third vibrator which vibrates in the first direction; and a fourth vibrator which vibrates in a second direction, which is perpendicular to the first direction.
