PROBLEM TO BE SOLVED: To prevent the positional deviation of a picture display device by providing the lens of a pair of spectacles with a positioning part for positioning the picture display device. SOLUTION: The picture display device 3 can be attached to/detached from the spectacles and it is mounted to the spectacles when picture observation is required. Light projected from a liquid crystal panel 7 is projected to a user's eye E through an enlarging lens 8 by power supplied from a battery specially provided through a lead wire, whereby a user can observe the picture. At such a time, the attaching hole 4a of the lens 4 is fit to the pin 8b of the lens 8, so that the mounted position of the device 3 is fixed. By forming the hole 4a at a position in accordance with the user's eye at the time of purchasing the spectacles, the picture is always projected to the user's eye E. Therefore, the device 3 need not be positionally adjusted every time it is mounted, and the handleability of the spectacles mounted type display device is improved.
