摘要： This invention relates to a transmissive liquid crystal display including a light source (BL), a reflective linearly-polarizing layer (Pr1), a birefringent layer (A) having specific optical properties and specific retardation properties, a light source-side absorptive linearly-polarizing layer (P1), a liquid crystal cell (LC), and a viewer-side linearly-polarizing layer (P2) which are arranged in this order. In the transmissive liquid crystal display of the invention, light leakage is suppressed in oblique directions so that black brightness can be reduced. A reduction in contrast in the normal direction can also be suppressed, which is caused by the distribution of light to the normal direction.

摘要： An apparatus includes a two-sided prism sheet, and an optical path conversion unit with linear prisms. Each apex angle of the prisms increases the closer the linear prism is formed to the center in the light guide direction, and when a pair of inclined surfaces of each of the prisms has a first inclined surface and a second inclined surface, an inclination angle of the second inclined surface is larger than the one of the first inclined surface. Among the prisms, inclination angles e1 and e2 of a pair of inclined surfaces of a linear prism formed closest to the center and an inclination angle c of the first inclined surface and an inclination angle d of the second inclined surface of a linear prism formed closest to the side end surfaces at which the light sources are disposed satisfy a relationship 2×c

摘要： A pretensioner is provided, of which the cylinder, including a restriction portion, can be inexpensively formed, the cylinder having the restriction portion for positioning a gas generation unit to be mounted to a cylinder, and a pretensioner manufacturing method for manufacturing such a pretensioner is provided. In the pretensioner, since the cylinder is molded by forging, an inexpensive material compared with a stainless pipe member can be used for the molding. In addition, since the positioning portion can be molded during forging-molding for molding the entire cylinder, cost can be reduced even in this regard.

摘要： A directional diffusion film with diffusion properties that vary depending on the incidence angle is characterized in that a diffusion axis direction is in the range of 20° to 50° with respect to a normal direction of the film, and a diffusion half-value angle is at least 20° and lower than 90°. The diffusion axis direction is a light irradiation direction in which the strongest diffusion light is obtained when the film is irradiated with light. The diffusion half-value angle is a diffusion angle at which intensity of outgoing diffusion light at a plane A is 50% of the peak intensity, with the plane A containing the normal direction and the diffusion axis direction of the directional diffusion film, when collimated light is incident at an incidence angle of 30° from the normal direction of the directional diffusion film in the plane A. A polarizing plate containing the directional diffusion film. An LCD device containing the directional diffusion film.
