ABSTRACT:
There are provided: a display surface (20) (mixed picture display part) for assigning a plurality of pieces of video information, respectively, to a plurality of a first divided area (S-I), a second divided area (S-II) and a third divided area (S-III), so as to display the plurality of the pieces of the video information on the display surface (20); a first picture separating mechanism disposed on the display surface (20) corresponding to the first divided area (S-I) of the plurality of the divided areas (S-I, S-II, S-III), and defining a predetermined polarizing direction; a second picture separating mechanism disposed on the display surface (20) corresponding to the second divided area (S-II) and the third divided area (S-III) of the plurality of the divided areas (S-I, S-II, S-III), and defining a predetermined polarizing direction different from the polarizing direction of the first picture separating mechanism; mirrors (optical means) (31, 32) disposed rightward and leftward relative to the display surface (20) in such a manner as to form respective predetermined angles relative to the display surface (20); and a third picture separating mechanism (40) defining a polarizing direction same as the polarizing direction of the first picture separating mechanism, and allowing a picture displayed on the display surface (20) and a picture displayed on the mirror (31, 32) to pass through the third separating mechanism (40) for a viewer to view the pictures.
