摘要
An optical lens system in accordance with the present invention is arranged so that, when the micro-lens has a curved surface satisfying an inequality of (n2/n1)×sin(&thgr;max)≧1, where n1 indicates an index of refraction of a medium constituting one side of the curved surface of the lens, n2 (n1n2) indicates an index of refraction of a medium constituting the other side of the curved surface of the lens, &thgr; indicates an incident angle of the light with respect to a plane-normal of the curved surface of the lens when the light from the light source is directed to the curved surface of the lens of the micro-lens from a side of the medium having the index of refraction of n2, and &thgr; max indicates a maximum value of the angle &thgr; in the curved surface of the micro-lens, the micro-lens array is provided so that the light from the light source is directed to the micro-lens from the side of the medium having the index of refraction of n1. When using such an optical lens system as an image display apparatus of projection-type, it is possible to obtain the bright projection image.
