    摘要： Provided is an optical fiber cable which allows for high-quality signal transmission in short-distance transmission. The optical fiber cable is designed for use in optical communication based on transmitting an optical beam from a light-emitting device, to a light-receiving device. The optical fiber cable has: a proximal end which is one end thereof on the side of the light-emitting device, and a distal end which is the other end thereof on the side of the light-receiving device, wherein an optical beam returning from the side of the distal end toward the side of the light-emitting device has an M2 factor of 1.7 or more; and a length of 50 m or less.

    摘要： There is provided a display device exhibiting a good color reproducibility, even when observed through polarized sunglasses. A display device comprises a polarizer a and an optical film X on a surface on a light emitting surface side of a display element, wherein L1, which is the light incident vertically on the optical film X, among light incident on the optical film X from the display element side, satisfies a specific condition, and L2, which is the light emitting vertically from the light emitting surface side of the optical film X, and passing through a polarizer b having the absorption axis parallel to the absorption axis of the polarizer a, satisfies a specific condition.

    摘要： Provided are an optical resin and an optical member using the same, both orientation birefringence and photoelasticity birefringence of the optical material being deadened and generally eliminated. The optical material consists of a composite constituent system of three or more constituents including a copolymerization system of monomer-element number not smaller than two, combination and constituent ratio of the composite constituent system being set so that both orientation birefringence and photoelasticity birefringence of the optical material are deadened at the same time and 5.0×10−5 or less is given under a condition that principal chains of the copolymerization system have degree of orientation equal to 0.03, and further a photoelasticity constant not greater than 1.0×10−12 (Pa−1) is obtained. The composite constituent system may contain an additive containing a low molecular weight compound which has an anisotropic polarizability and can be orientated in a polymer. The composite constituent system may consist of a copolymerization system of monomer-element number not smaller than three. Optical members produced by applying molding to the optical hardly show birefringence if external force is applied.
