Patent ID: 7738179

Claim:
An image display device that: (i) projects, via a relay optical system, lights emitted from each of two two-dimensionally light emitting type photoelectric devices which are perpendicular to a light beam emitting direction onto first and second light diffusing bodies that are independent of each other relative to right and left eyes of a user, and (ii) projects and images transmitted images of said light diffusing bodies onto a retina in the respective right and left eyes of the user via first and second eyepiece optical systems which respectively correspond to the first and second light diffusing bodies, wherein the imaged transmitted images are wide range images having a field of view angle of at least ±22.5 degrees, wherein said two two-dimensionally light emitting type photoelectric devices are each a reflection type liquid crystal device element, and wherein the image display device further comprises: one light source, a first polarization beam splitter that divides light emitted from said light source into P-polarized light and S-polarized light, and an optical system that leads each of the divided P-polarized light and S-polarized light respectively to said two two-dimensionally light emitting type photoelectric devices, thereby illuminating said two two-dimensionally light emitting type photoelectric devices, wherein the optical system leads the lights reflected by each of said two two-dimensionally light emitting type photoelectric devices to said relay optical system via a second polarization beam splitter, and wherein the reflected lights are one of the P-polarized light converted from the S-polarized light and the S-polarized light converted from the P-polarized light.
