Abstract
An image forming system is provided which includes an optical sheet and an image projector. The optical sheet is constructed by joining a plurality of sheet members with adjoining sheet members meeting to form a joint line. The image projector produces an image and projects the image to the optical sheet through a projection optical system. The relative positional relationship between the image projector and optical sheet is such that the optical axis of the projection optical system included in the image projector perpendicularly intersects the joint line in the optical sheet. Thus, reflection or scattering of light at the joint line is minimized.
