<p>PROBLEM TO BE SOLVED: To provide a light guide plate which prevents a print lack at an edge of the light guide plate being a problem of screen printing, and in which a complete luminance-equalized fine pattern is formed on a reflection face in a relatively short time (shortening of processing time), and a manufacturing method of the light guide plate.SOLUTION: In a manufacturing method of a light guide plate in which light is made incident from an end face and emitted from one emission face of a surface, and a luminance-equalized fine pattern is formed on a reflection face opposing the emission face, a protrusive pattern is printed on the whole surface by screen printing, next, a print lack is inspected, a recessive pattern is formed by boring a print-lacked portion by a laser, and the luminance-equalized fine pattern is formed.</p> |
