An object of the invention is to form a projecting image of smooth image quality inconspicuous in a joint in a stable state. With respect to image light passing through a second birefringent plate 28j set to a first state, an image light portion branched by a first birefringent plate 28i is further branched in the Y-direction. An image IM3 constructed by an original pixel PX0, a pixel PX2 corresponding to its branching image, and a black matrix area BA is formed on a screen. With respect to the image light passing through a second birefringent plate 28j set to a second state, the image light once branched by the first birefringent plate 28i is returned in the -Y direction. As this result, an image constructed by the black matrix area BA and an image provided by overlapping the branching image of the original pixel PX0 with the original pixel PX0 is formed on the screen. Namely, the same image IM3' as an original image IM1 is formed on the screen. |
