A display device may include a display part, a sensor, an actuator, and a control device. The display part may include an operation surface on which a touch operation is performed by a user. The sensor may detect a displacement of the display part by the touch operation. The actuator may be configured to vibrate the display part. The control device may be configured to vibrate the display part with the actuator when the displacement of the display part by the touch operation is detected. The display part may be displaceable between a restriction position for restricting the displacement of the display part via the actuator and an allowance position for allowing the displacement of the display part via the actuator. The control device may be further configured to adjust the display part into the allowance position when a user operation for the touch operation is detected.
