The display unit displays two-dimensional picture. When the panel unit is at the first position, the microlens unit confronts the display unit with the spacing substantially equal to the focal length of the microlens unit. Therefore, the two-dimensional picture is visualized as a pseudo-stereoscopic picture. On the other hand, when the panel unit is at the second position, the microlens unit does not confront the display unit, and hence a user can directly see the two-dimensional picture on the display unit.
