METHOD FOR MANUFACTURING LIGHT GUIDE PLATE

摘要

PROBLEM TO BE SOLVED: To provide a method capable of manufacturing a light guide plate having reflective dots stably and with high productivity.

SOLUTION: The method for manufacturing the light guide plate 1 includes: a process to perform dot-pattern printing with ink droplets on a surface of a translucent resin sheet 11 while moving the translucent resin sheet 11 continuously or intermittently; and a process to form reflective dots from the ink pattern-printed. The ink droplets are supplied from a plurality of nozzles which are arranged and fixed throughout the whole width direction in a region on the surface of the translucent resin sheet 11, where the reflective dots are formed.
