Abstract:
[Problem] To provide a display device and electronic equipment that implement both a force feedback function and a haptic function and that have high strength. [Solution] A display device according to the present invention comprises a display panel, a touch panel, a spacer, a haptic panel, and a piezoelectric actuator. The touch panel is placed on the display panel and has a first principal surface on the side of the display panel and a second principal surface on the side opposite to the first principal surface. The haptic panel is placed on the spacer and has a third principal surface facing the second principal surface across a space and a fourth principal surface opposite to the third principal surface. The piezoelectric actuator is placed on the third principal surface and causes vibration. A first thickness, which is defined as being the thickness between the second principal surface and the fourth principal surface is 0.5-1.5 mm, and is also equal to or larger than a thickness, which is obtained by adding 0.3 mm to a second thickness defined to be a thickness between the second principal surface and the third principal surface, and equal to or smaller than a thickness that is obtained by adding 1 mm to the second thickness.
