<P>PROBLEM TO BE SOLVED: To provide a back-light guide plate for liquid crystal display device capable of shortening a period of time required for a computer simulation and a working time. <P>SOLUTION: A plurality of pairs of light sources 22 and arrangement patterns 35 of optical control elements corresponding to the light sources are adjacently provided. A plurality of light sources 60, 61 and 62 are provided. A plurality of pairs of respective light source and respective arrangement patterns of optical control elements corresponding to the plurality of kinds of light sources are made into a fixed adjacent column and the columns are adjacently provided in a plurality of rows. The outside shape of a region, where the arrangement pattern of the optical control element is formed, is a rectangular shape. A first metal stamper, where the arrangement pattern of the optical control element is formed, is used as an original plate to replicate a second metal stamper as a mother plate and the light guide plate is formed by using a resin. <P>COPYRIGHT: (C)2007,JPO&INPIT |
