摘要： 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.

摘要： A transmittable light-scattering sheet (a transmitting type light-scattering sheet) of the present invention comprises a plurality of layers, each having a bicontinuous structure composed of a plurality of polymers. The layers differ from each other in average period size of the bicontinuous structure. The sheet may comprise, for example, a first layer having a bicontinuous structure (e.g., the average period size of the bicontinuous structure of 1.5 to 4 &mgr;m) and a second layer each having a bicontinuous structure (e.g., the larger average period size of the bicontinuous structure than that of the first layer by 0.5 to 8 &mgr;m). In the sheet, the first layer may be next to the second layer. The ratio of the period size of the first layer to that of the second layer may be the first layer/the second layer=1.3/1 to 4/1. Such a sheet can impart a directionality to a reflected light.

摘要： A backlight system (30) includes a light emitting section (31) and an imaging optical system. The imaging optical system includes a first microlens array (MLA1) and a second microlens array (MLA2). The lenses (1A) separates the beams of light emitted from the light emitting section (31) by RGB, and causes them to be converged at a pitch same as a pitch at which the picture elements are arrayed. The lenses (2A) are provided in one-to-one correspondence to the picture elements such that the lenses (2A) have their respective focal points at positions onto which beams of light having passed through the lenses (1A) are converged. The lenses (2A) thus deflect the beams of light which have passed through the lenses (1A) in a substantially vertical direction with respect to the display surface of the liquid crystal panel.
