In an optical sheet which is used for light control illumination in a backlight unit for a display, in order from an incident side of an illuminating light, there are provided at least a light scattering layer which scatters the illuminating light toward an outgoing surface side, an adhesion layer or an adhesive layer, a light reflection layer which reflects light scattered by the light scattering layer toward the light scattering layer side, and a lens sheet whose flat rear face is fixed to the other side of the light reflection layer, and in which a plurality of unit lenses are disposed on the surface. Opening portions corresponding to the respective unit lenses one-to-one are provided to the light reflection layer, and thickness of the adhesion layer or the adhesive layer is thinner than that of the light reflection layer.

Optical sheet, and backlight unit and display using the same

A transmission screen includes a Fresnel lens sheet through which light is projected from a projector to a lenticular lens sheet arranged on a viewer side, as approximately parallel light, and the lenticular lens sheet receiving light passing through the Fresnel lens sheet, and emitting the approximately parallel light while horizontally widening, by means of a group of cylindrical lenses which are horizontally in parallel, wherein in at least one of the Fresnel lens sheet and the lenticular lens sheet, on a surface of a light diffusing substrate, in which a light diffusing material is dispersed, irregularities which constitute a lens section is formed, and in the light diffusing substrate, dispersion density of the light diffusing material differs in at least two layers in the thickness direction.

Light diffusing substrate, transmission screen, and display device

A transmission screen includes a Fresnel lens sheet through which light is projected from a projector to a lenticular lens sheet arranged on a viewer side, as approximately parallel light, and the lenticular lens sheet receiving light passing through the Fresnel lens sheet, and emitting the approximately parallel light while horizontally widening, by a group of cylindrical lenses which are horizontally in parallel, wherein in at least one of the Fresnel lens sheet and the lenticular lens sheet, on a surface of a light diffusing substrate, in which a light diffusing material is dispersed, irregularities which constitute a lens section is formed, and in the light diffusing substrate, dispersion density of the light diffusing material differs in at least two layers in the thickness direction.

A thermal transfer recording medium including a substrate, and a thermal transfer recording layer formed on the substrate and mainly containing a coloring pigment, an amorphous organic high polymer and colorless or light-colored fine particles, the thickness of the thermal transfer recording layer being in the range of 0.2&middot;m to 1.0&middot;m, wherein the mixing ratios of the coloring pigment, the amorphous organic high polymer and the fine particles are confined to 20-60 parts by weight, 40-70 parts by weight and 1-30 parts by weight, respectively. An image-forming method using the thermal transfer recording medium, and an image-bearing body formed from the thermal transfer recording medium are also disclosed.

Thermal transfer recording medium, image-forming method and image-bearing body

A thermal transfer recording medium comprising a substrate, and multi-color thermal transfer recording layers, each of the multi-color thermal transfer recording layers being repeatedly formed for each color along the longitudinal direction of the substrate, wherein each of the multi-color thermal transfer recording layers contains a coloring pigment, an amorphous organic polymer and fine particles. One of the multi-color thermal transfer recording layers is formed to have a larger thickness than the other of the multi-color thermal transfer recording layers. Each of the multi-color thermal transfer recording layers which are successively transferred, excluding the color thermal transfer recording layer to be transferred latest, is formed to have an average thickness of 0.6 &mgr;m or less.
