Abstract: PURPOSE: A head mounted display(HMD) using a reflective image is provided to prevent the degradation of optical efficiency by converting a diffused beam into a parallel beam. CONSTITUTION: A diffusing unit(40) generates a diffused beam. A collimating unit(42) receives the diffused beam incident from the diffusing unit(40) and converts the diffused beam into a parallel beam to emit the converted parallel beam. An image source(44) is a single reflective type. The converted parallel beam from the collimating unit(42) reaches on the image source(44) passing through a prism. The prism divides then a beam reflected from the image source(44) into left and right beam in order to make two images to be provided to two eyes of a user, respectively. The collimating unit(42) is comprised of a Fresnel lens.
