An image display system includes a light valve 14 for providing image information to light converged by a converging lens 13 and for emitting the light, a projective optical system 20 including a refractive optical lens 21 for projecting the light from the light valve 14 and a convex mirror 22 for reflecting the light from the refractive optical lens 21 by using a reflecting surface thereof having negative power and for enlarging and projecting the reflected light, and a display 30 for receiving the light from the projective optical system 20 by way of a receiving surface 30 A, wherein the light valve is placed away from an optical axis 23 of the projective optical system 20 and between a front surface of the display 30 and a rear surface of the projective optical system 20.
