    摘要： The present invention discloses a method for producing plastic optical member comprising a core region and a clad region. The method comprises carrying out polymerization of a polymerizable monomer, thereby obtaining an area corresponding to the core region. The Polymerization is carried out in the presence of a polymerization initiator having a ten-hour, half-life decomposition temperature T h (°C) (T b - 20 ≦ T h ; T b is the boiling point (°C) of the polymerizable monomer), at an initial polymerization temperature T 1 (°C) (T b -10 ≦ T 1 ≦ T g ; T g is the glass transition point (°C) of the polymer made of the polymerizable monomer) , for a period which is equal to or longer than 10% of the half-life of the polymerization initiator at T 1 ; and further carried out at an elevated temperature T 2 (°C) (T g ≦ T 2 and T 1 2 ) .

    摘要： A light-scattering light guide and its manufacturing, wherein a beam having a relatively small sectional area can be transformed into a beam having a relatively large sectional area with a high efficiency and uniformity. Additionally, applied optics apparatuses such as a backlight source, an optical branching device, and an optical mixing device, which utilize the characteristic of the light-scattering light guide effectively. The light guide is obtained by utilizing various ununiform refractive-index structures produced in polymerizing organic materials. According to the application, the values such as of the scattering power (effective scattering projection parameter E) are selected. The mechanisms, by which the ununiform refractive index structures are formed by the process of polymerizing organic materials, is based on, e.g., the differences in compatibility, reactivity, and density, etc. among the organic materials.

    摘要： The present invention aims to provide an image display device including an optical film having a thickness suitable for practical use without including any special inorganic material, wherein the image display device has high color rendering properties and is capable of minimizing the occurrence of blackout and interference colors (rainbow unevenness) even when the image display device includes light sources that emit light having a narrow emission spectrum. The present invention provides an image display device including an optical film having an in-plane birefringence and a polarizer in this order, wherein the optical film and the polarizer are disposed to form an angle of about 45° between a slow axis of the optical film and an absorption axis of the polarizer, the optical film has a retardation of 3000 nm or more, and light incident on the optical film provides at least 50% coverage of ITU-R BT.2020.

    摘要： A polymer is inserted into a cylinder (1) and heated, and a pressure is then applied to the polymer so as to extrude the same in the shape of a fiber from a nozzle (3). In the meantime, a diffusible material is injected from a nozzle (5) into the central portion of a molten liquid of this polymer through a thin-tube cylinder (4), and it is diffused gradually from the central portion of the molten polymer to the circumferential portion thereof as it flows toward a discharge port of the nozzle (3). The material extruded from the nozzle (3) is air-cooled and taken up around a drum (7) via a roller (6). The fiber-like molded product provides a distribution of refractive index varying continuously from the center thereof toward the circumferential portion thereof, and serves as a convergent or divergent plastic light transmitter. Conversely, even when the molten liquid of the polymer is extruded from the nozzle (5), a light transmitter having a region in which a refractive index varies continuously can be obtained. A proper number of the cylinders and various kinds of materials to be supplied to the cylinders can be selected.
