<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing, with good productivity, a raw fabric of an optical laminate capable of condensing diffusion light into parallel light and functioning as a collimator, to provide the optical laminate and a backlight unit for a liquid crystal display using the same, and to provide the liquid crystal display. <P>SOLUTION: In the method for manufacturing the raw fabric of the optical laminate, cholesteric liquid crystal layers 61R, 61G and 61B of Grandjean alignment which are used in combination and have a collimator function for condensing diffusion light from a light source into parallel light are serially stacked on an elongated quarter wave plate 62 and integrated with each other. The optical laminate is formed by cutting the rolled web obtained by this method. The backlight unit for the liquid crystal display has the optical laminate. The liquid crystal display has the backlight unit. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
