Relates to the present invention is an optical system for a pico projector that may be attached to the generated image relates to an optical system used in the projector to enlarge the projection screen or the like, and more particularly to such small mobile devices such as mobile phones, the illumination optical unit the light in the optical system for pico projector that is passed is incident to the DMD device through internal reflection structure portion projecting optical this light reflected from the DMD device through an internal reflective structure light emitted from the inside reflection structure is one piece of the tilting relay including the prism structure of the lens and the one sheet, and the tilt relay lens is inclined in correspondence to the first surface of the prism structures so that the relay in a first face of the prism structure facing the light incident from the illumination optics and the illumination optics positioned, the prism structure of the prism structures facing and bends toward the DMD device an incident light from the tilt relay lens, and the light reflected from the DMD device converts the light path toward the optical parts of projection, and the DMD element the second surface is formed to have a convex curvature towards the DMD device, the third face of the prism structure facing the projection optical unit is an optical system for pico projector, characterized in that formed so as to have a convex curvature toward the the projection optical to provide.
