1. A display device comprising:
a display panel;
a touch sensing layer which senses a touch input of a user;
a first vibration device which is disposed on a first surface of the display panel and generates vibration according to driving voltages,
wherein the first vibration device generates a first vibration during a first situation, and the first vibration device generates a second vibration during a second situation,
wherein the number of times of increasing the amplitude of the first vibration is N where N is a positive integer, and the number of times of decreasing the amplitude of the first vibration is M where M is a positive integer,
wherein a time period of duration of the first vibration is different than a time period of duration of the second vibration, and
wherein the first vibration device generates a third vibration in response to touch a first icon, and the first vibration device generates a fourth vibration in response to touch a second icon,
wherein a frequency of the third vibration and a frequency of the fourth vibration is larger than a frequency of the second vibration.
