ARRANGEMENT PATTERN DESIGN METHOD, LIGHT GUIDE PLATE PRODUCTION METHOD, PRODUCTION METHOD FOR SURFACE LIGHT SOURCE DEVICE, AND PRODUCTION METHOD FOR TRANSMISSIVE IMAGE DISPLAY DEVICE

摘要

An object of the present invention is to provide a method of designing an arrangement pattern of light scattering dots in which pattern unevenness of light scattering dots is hardly generated. A layout pattern designing method according to an embodiment is a method of designing an arrangement pattern of a plurality of light scattering dots in a light guide plate, in which a dot formation surface of a light guide plate base is divided into a plurality of virtual areas, A step (S12) of setting a plurality of virtual cells to be a target for forming light scattering dots for each virtual area, a step (S12) of setting a virtual light scattering dot (Step S13) of creating an initial arrangement pattern of the virtual light scattering dots by applying the error diffusion method to the initial arrangement pattern, thereby disposing the virtual light scattering dot constituting the initial arrangement pattern at a plurality of size levels , And a step (S14) of creating an arrangement pattern for forming light scattering dots.
