<P>PROBLEM TO BE SOLVED: To provide an optical substrate capable of improving the evenness of luminance of light emitted from an emission surface and improving the productivity of an electrooptical apparatus, to provide a manufacturing method of the optical substrate, and to provide a planar lighting device and a liquid crystal display system provided with the optical substrate. <P>SOLUTION: Droplets of substrate layer-forming material are ejected to an emission surface 22b of a light guide plate 22 to form a liquid film, the liquid film is cold-set or heat-set and, thereby, a substrate layer 24 which can repel the droplets of lens-forming material and refracts and diffuses light made incident from the emission surface 22b is formed. Further, droplets of the lens-forming material are ejected to a lens-forming surface 24a of the substrate layer 24 and the ejected droplets are irradiated with ultraviolet rays so that microlenses are formed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
