An image display device capable of detecting an object in a space where a 3D visualized image is formed without feeling the existence of a mechanism for position detection. The image display device includes: display unit (11) for displaying a 2D image (1); an optical panel (12) arranged in front of an image display plane (15a) of the display unit (11) and forming a 3D visualized image (2) based on the 2D image (1) in a forward space (3) spreading in front of the optical panel (12); recognition unit arranged behind the optical panel (12) for optically recognizing the an object (5) coming into the forward space (3) via the optical panel (12); and position detection elements (14) for detecting the coming position of the object (5) into the forward space (3) according to the recognition result by the recognition unit.
