An imprint apparatus includes: a mold that forms a pattern in a resin on a base plate; a press unit that presses the mold against the resin; a flow channel that is formed by a wall of the mold and a surface of the resin, air flowing along the wall and the surface; a supply unit that supplies air to the flow channel; wherein the supply unit supplies air with a first pressure to the flow channel when the mold makes contact with the resin.

Imprint apparatus and imprint method

A reflector has a curved part covering the light source and a pair of end parts extending at the two sides of the curved part. The inside surface of each end part has a plurality of substantially parallel projections or depressions. The light-guiding plate has an incident surface and an emission surface substantially perpendicular to the incident surface, the incident surface having a plurality of projections or depressions extending substantially parallel to the emission surface. Also, the reflection surface of the light-guiding plate has projections.

Light-guiding plate, lighting device and display device

A light guide member illuminates with uniform light intensity distribution using the point light source light. On the lower end of the light guide member having a pair of side faces disposed oppositely, a groove is provided for receiving light output from each point light source and diffusing the above received light to at least three directions from the incident side toward the output side. Light components having directions using side-face reflection are generated in the light guide member, enabling light output to multiple directions from the cylindrical-shaped light guide member, and uniform illumination over a wide range. By using the ring-shaped light guide member, cost reduction is effectively achieved, and miniaturization of the illumination mechanism and the image capturing mechanism can also be attained.

Light guide member, illumination apparatus, and image capturing apparatus using the same

A light-guiding plate, an optical source device and an electronic device. The light-guiding plate including an incident surface, and an emission surface substantially perpendicular to the incident surface. The incident surface has a surface substantially perpendicular to the incident surface, and has projections or depressions extending substantially parallel to the emission surface. The incident surface has flat planes among the projections or depressions.

A lighting device including a light guide plate, a light source unit disposed on the side of the light guide plate and a polarization separation element disposed between the light guide plate and the light source unit. The polarization separation element is used for transmitting linearly polarized light in a first polarized direction and reflecting linearly polarized light in a polarized direction normal to the first polarized direction. The light source unit includes a pillar-shaped light guide which light exits at a first side surface, a spot light emission source disposed on the end surface of the pillar-shaped light guide, and a reflecting layer disposed on a second side surface of a prism surface opposed to the first side surface for reflecting light from the spot light emission source.
