PURPOSE:To reduce the manufacturing cost of a lens array and to improve the precision of picture propagation by employing the united structure wherein nearly hexagonal lens parts are arranged without any gap. CONSTITUTION:A material which is relatively strong is formed in a hexagonal prism 6 and one end is polished into a curved surface 7; and those materials are arranged without any gap to an optional size and adhered together to form a pattern 8. Then, the pattern 8 is brought into press contact with clayey ceramic 9 by a press, etc., to transfer the ruggedness of the pattern 8 completely and then a heat treatment is carried out to obtain a mold 9' made of hard ceramic. An optional material for a lens, e.g. melted plastic 10 is charged in the ceramic mold 9' and cooled after press-contacting to manufacture a lens 10 with array structure. |
