OPTICAL DEVICE AND DISPLAY DEVICE USING IT

摘要

An optical device comprising an image unit consisting of a plurality of lens substrates each formed on the front and rear faces thereof with lens arrays and a display unit disposed on an object surface with respect to the image unit and displaying an image to be projected by the image unit, characterized in that the lens array is a cylindrical lens array and the generating line of a cylindrical array formed on the front face and the generating line of a cylindrical array formed on the rear face cross each other. The lens substrate formed on the front and rear faces thereof with cylindrical lens arrays is used to provide a small, lightweight optical device of a full-size or magnified image system.
