INPUT DISPLAY DEVICE

Provided is an input display device (100) capable of improving determination accuracy of a rotation operation on a three-dimensional operation unit.An input display device (100) of the present invention includes a display (110) configured to display an image, a capacitive touch panel (120) attached to the display (110) and including a knob (130) that is at least one three-dimensional operation unit on the front face, and a sensing unit (150) configured to measure an electrostatic capacitance of the touch panel (120) and senses an operation on the touch panel (120) based on the measured electrostatic capacitance. The sensing unit (150) senses the rotation amounts of all the fingers touching the knob (130), and determines that the rotation operation on knob (130) has been performed when a sensed rotation amount of any of the fingers reaches a threshold value.
