ABSTRACT:
A projection type image display apparatus includes a projection optical system the projects light emitted from an organic EL element onto a target object. The projection optical system has a characteristic non-telecentric toward the EL element with principal rays which pass through the median point of the aperture pupil that captures light diffusively emitted from the EL element converging when seen from the EL element at a pixel position where the object height on the EL element from the optical axis of the projection optical system reaches a maximum.
