    摘要: A light source device outputs illumination light with highly uniform tint. The light source device is comprises a scattering guide provided with scattering power inside, a light supplier to supply light to an end face portion of the scattering guide. Light is introduced into the scattering guide plate to be followed by emission from an emission face of the scattering guide. Scattering efficiency is intentionally balanced in a long wavelength region and in a short wavelength region so that regions near the end face and far from the end face are approximately equal in color temperature of output light. Relation between Q(R), efficiency in a long wavelength region, and Q(B), scattering efficiency in a short wavelength region, are designed so that k=Q(B)/Q(R) falls within a range 0.75≦k≦1.25.

    摘要: A non-birefringence optical resin material is obtained by forming a transparent matrix from a polymeric resin having an orientation birefringence with a positive or negative sign, adding a low molecular weight substance exhibiting an orientation birefringence with a sign opposite to that of the orientation birefringence of the polymeric resin for the matrix and thus offsetting the orientation birefringence of the polymeric resin for the matrix with the orientation birefringence of the low molecular weight substance.

    摘要: Light is supplied into a light incident surface 2 from a fluorescent lamp L enclosed by a silver foil sheet R, and parallelized illuminating light flux is taken out from a light exit surface 3. On a back surface 4 side of a light flux parallelizer 1, across or without a thin air layer 5, a polarization converter &Sgr; is disposed. The polarization converter &Sgr; reinforces the polarization function of the surface light source device through polarization conversion action accompanying reflection in the prism. At a position confronting the light exit surface 3 across an air layer 7, a polarization separating plate 8 is disposed. At a further outside, across an air layer 9, an exit light direction modifier 10 is disposed. A bright polarized illuminating light flux is emitted from a light exit surface 11. When applied to a backlight of a liquid crystal display, a liquid crystal display panel is disposed at a further outside of the exit light direction modifier 10.

    摘要: A fluorescent lamp L is arranged in the vicinity of an incidence surface 2 of a light scattering guide plate 1. A prism sheet 4' having rows of prism elements and rows of lens elements on each side is arranged outside an exiting surface 5. The angles of inclination of slopes 4a and 4b satisfy a condition that .phi.a>.phi.b. The slopes 4a and 4b extend in the transverse direction of the light scattering guide plate 1, and slopes 4c and 4d extend in the longitudinal direction. A reflector 3 is arranged along a rear surface 6. Light emitted from the exiting surface 5 is efficiently propagated by an inner prism surface toward a forward direction, shifted in the transverse direction by an outer prism surface or the lens element surfaces 4c and 4d, and is then returned inwardly. The path histories of light emitted from the prism sheet 4' is diversified to improve visual characteristics. The peak level of brightness as viewed in the forward direction is improved and brightness is smoothly reduced according to deviation from the peak direction.

    摘要: An optical resin, of which the refractive index continuously changes in a specific direction, is produced by filling a polymerization container with a mixed solution containing at least one type of polymerizable monomer or polymerizable monomer sol and at least one type of substance whose solubility parameter differs by 7 (cal/cm.sup.3).sup.1/2 or less and refractive index by 0.001 or more from those of a polymer produced by polymerization of the monomer, and by subjecting the mixture to polymerization reaction by applying heat or energy rays to the container from outside so that the polymerization reaction starts and progresses preferentially from a particular region of the mixture, thus forming a concentration gradient of the substance having different refractive index.The polymerization container may be made of a polymer which swells and dissolves into the mixed solution from an inner wall thereof. After completing the polymerization reaction, the optical resin is subjected to hot drawing to obtain an optical conductor. Further, post-treatment based on crosslinking reaction is applied to improve heat resistance.
