Abstract
A light-diffusing layer 16 having at least a bicontinuous phase structure is formed by coating a substrate 14a with a coating liquid composition containing a plurality of resins being different in refractive index with each other, drying the substrate, and heating the resultant to cause spinodal decomposition from the resin-containing layer on a transparent substrate. A transparent conductive layer (or a transparent electrode) 17 may be formed on the light-diffusing layer 16 of the substrate 14a. A liquid crystal cell 13 of a reflective liquid crystal display apparatus may be formed by facing the transparent conductive layer 17 with a reflection electrode 19 formed on the other substrate 14b, and sealing a liquid crystal 18 between a pair of electrodes, 17 and 19. The present invention, therefore, provides a light-diffusing layer capable of uniformly and brightly displaying an image on a screen in a reflective liquid crystal display apparatus of an internal light-diffusing layer system in which the light-diffusing layer is formed on a substrate of a liquid crystal cell.
