An image display device is provided with a cover that covers a drive circuit unit and an optical unit and a falling-down detecting unit that detects the falling-down of the image display device. The falling-down detecting unit further detects, based on force to be applied to the falling-down detecting unit in a state in which the cover is attached to the image display device, whether or not the cover is detached from the image display device. |
