PURPOSE: To observe a stereoscopic image without the sense of incompatibility by respectively providing view limiting frames at the polarizing filter parts for left and right eyes of the spectacles for stereoscopic image to observe a laterally bisected monitor display picture.

CONSTITUTION: Since crossing right and left pictures R and L displayed through left and right side areas 23A and 23B of a polarizing filter 23 mounted at a monitor are observed by right and left eyes through polarizing filters 33 for right and left eyes of the spectacles for stereoscopic image, a stereoscopic image G can be observed at that crossing position. At such a time, since only the right picture R reaches the right eye and only the left picture L reaches the left eye by providing view limit frames 110A and 110B, only the stereoscopic image can be observed without observing unnatural images around the stereoscopic image G. Further, since the left and right pictures L and R are separately displayed by laterally bisecting the monitor, the stereoscopic image can be observed with the sense of a planar image even when observing the monitor without mounting the spectacles for stereoscopic image.
