Disclosed is an image display device which appropriately switches the display mode according to whether or not a visual aid is in contact with or close to part of the body of a user. Specifically disclosed is an image display device (1) provided with a display unit (11) which performs display in either a three-dimensional image display mode in which an image for the left eye to be visually recognized through a left eye portion (21L) of a visual aid (2) and an image for the right eye to be recognized through a right eye portion (21R) of the visual aid (2) are displayed while being temporally or spatially separated or a two-dimensional image display mode in which either the image for the left eye or the image for the right eye is displayed. The image display device (1) receives from the visual aid (2) a wear signal (241) indicating that the visual aid is in contact with or close to part of the body of a user, and on the basis of the reception state thereof, switches the display mode of the display unit (11) between the three-dimensional image display mode and the two-dimensional image display mode.
