Provided is a light-emitting device having an excellent light emission performance irrespective of its small thickness. The light-emitting device includes a base having a surface; one or more light sources that are provided on the surface of the base, and each have an optical axis; a reflective lens provided to interpose the light source between the reflective lens and the base; a reflective sheet that is provided to surround the light source along the surface of the base, and includes a first surface that makes a first angle relative to a plane that is substantially orthogonal to the optical axis to allow the first surface to be away also from the base as the first surface is away from the light source; and a light diffusion member provided to interpose the light source, the reflective lens, and the reflective sheet, between the light diffusion member and the base.

Light-emitting device, display apparatus, and lighting apparatus

An object of the present invention is to provide a light source lens that makes it possible to improve unevenness in a luminance distribution, an illumination unit, and a display unit. A light source lens () according to the present disclosure includes an incident surface on which light from a light-emitting device is incident, and an exit surface () that has a diffusing function at a center part () for light incident through the incident surface as well as a light-condensing function at at least a portion of an intermediate part () and a peripheral part () for the light incident through the incident surface.

Light source lens, illumination unit, and display unit

An optical part includes a panel cover to be attached around a display area of a display element, a holder holding an optical element, a spring pressing the holder against the panel cover in order to place and rotatably attach the holder to the panel cover one over another, and a dust barrier cover provided on the holder, wherein the part of the holder in contact with the spring has an extension, which is integral with the dust barrier cover.

Optical part, optical unit and display apparatus having a dust barrier cover

A projection television apparatus includes: frame; rear projection screen; and projector unit for emitting image projection light beam onto rear of screen; wherein projector unit includes; illuminating means, image forming means for modulating light beams on basis of image information, and projection lens for projecting image onto screen; optical axis of projection light beam is bent with optical axis of projection lens; part extending from image forming means to projection lens is separated from light source side unit, and part extending from image forming means to projection lens is formed as integrally coupled body into image emergence side unit; support mechanism for supporting image emergence side unit with frame rotatably around optical axis of projection lens along plane orthogonal to optical axis, image adjusting mechanism by rotation for adjusting angle of rotation around optical axis of projection lens, and securing mechanism for image emergence side unit with frame are provided.
