| titleOfInvention | Lens substrate forming mold manufacturing method, lens substrate forming mold, lens substrate, transmissive screen, and rear projection TV |
| abstract | A lens substrate forming mold capable of forming a lens substrate excellent in light utilization efficiency and viewing angle characteristics, a manufacturing method capable of efficiently manufacturing the lens substrate forming mold, Provided are a lens substrate, a transmissive screen, and a rear projection TV that are excellent in utilization efficiency. A method for manufacturing a lens substrate forming mold includes a step of preparing a member with recesses 6 having a large number of spherical recesses 61, and the shape of the recesses 61 of the member with recesses by using the member with recesses as a mold. A step of forming a member with a spherical convex part having a corresponding spherical convex part of a spherical shape and a part of the spherical convex part are removed to form an aspherical convex part of the aspherical shape. A step of forming a member with a portion, and a step of obtaining a lens substrate forming die having a concave portion having a shape corresponding to the aspherical convex portion by using the member with an aspherical convex portion as a mold.
