LIGHT-GUIDE-PLATE CREATION METHOD AND DEVICE

摘要

Provided is a light-guide plate for a liquid-crystal-screen display device capable of obtaining a favorable visual effect. A light-guide plate is created by transferring printing data of a light reflection pattern stored in a computer to an inkjet printer, and using the inkjet printer to subject a substantially rectangular printing surface surrounded by the light-guide-plate top, bottom, left and right edge sections to reflection printing for randomly scattering light emitted from a light source to the interior of the light-guide plate. The printing data for conducting the reflection printing is created in a manner such that the printing concentration increases from edge sections in four directions corresponding to the edge sections in the four directions of the light-guide plate toward one or more high-concentration setting points that are set so as to be positioned in front of the respective edge sections on the opposite side. The reflection printing is conducted using white ink containing titanium oxide.
