摘要： A liquid crystal display apparatus includes a liquid crystal display panel including a liquid crystal cell between first second polarizing plates; and a surface light source device. The surface light source device includes a light source unit, a light guide plate for outputting first directivity light having directivity of maximum intensity in a first direction, which forms a predetermined angle from a normal direction of the light output surface in a plane approximately parallel to a light guiding direction of light, and having a high ratio of a polarized light component oscillating in the plane and a prism sheet being configured to convert the first directivity light into second directivity light directed in a second direction within a predetermined angle from the normal direction of the light output surface of the light guide plate while substantially maintaining a polarization state of the first directivity light.

摘要： A lens sheet and lens sheet unit include an imaging module and an imaging device which can be made thinner. A first lens sheet has light transmission parts having a unit lens shape, and light absorption parts disposed alternatively with the light transmission parts. A lens sheet unit, on the image sensor side of the first lens sheet, includes a second lens sheet. The second lens sheet has light transmission parts having a unit lens shape, and light absorption parts disposed alternatively with the light transmission parts. When viewed from the optical axis direction, the direction in which the light transmission parts are arranged and the direction in which the light transmission parts are arranged intersect at an angle. An imaging module and a camera are included with the above lens sheet and lens sheet unit.
