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

A backlight device that illuminates a transmissive liquid crystal panel is disclosed. The device includes: a plurality of light source substrates on which a plurality of light emitting devices irradiating illumination light are mounted; a bottom chassis having one surface to which the plurality of light source substrates are attached; a reflector having openings corresponding to the light emitting devices and through which the light emitting devices are exposed to one surface side, and reflecting the illumination light irradiated from the light emitting devices; a diffuser facing the one surface side of the reflector through a predetermined facing interval and internally diffusing the illumination light incident from the reflector; and an optical function sheet laminate combined with the diffuser on one surface side thereof, containing a stack of a plurality of optical function sheets and guiding the illumination light to the transmissive liquid crystal panel.

A backlight device that illuminates a transmissive liquid crystal panel is disclosed. The device includes: a plurality of light source substrates on which a plurality of light emitting devices irradiating illumination light are mounted; drive substrates having drive circuits for the light emitting devices and electrically connected to the light source substrates; a bottom chassis having one surface to which the plurality of light source substrates are attached; a reflector having openings corresponding to the light emitting devices and through which the light emitting devices are exposed, and reflecting the illumination light; a diffuser facing the one surface side of the reflector through a predetermined facing interval and internally diffusing the illumination light; and an optical function sheet laminate combined with the diffuser on one surface side thereof, containing a stack of a plurality of optical function sheets and guiding the illumination light to the liquid crystal panel.

A color selecting electrode of a cathode ray tube is prevented from being twisted to thereby suppress an electron beam from a mislanding. A metal thin plate (,) having vertically striped opening portions (,) is supported by frame members (,), (,) under a proper tension. The frame member (,) welded to the metal thin plate (,) is joined with a supporting member (,) extended in the longitudinal direction and the frame member (,) welded to the frame member (,) is joined with a supporting member (,) extended in the direction (Z-axis direction) perpendicular to a plane formed of the frame members (,). The supporting member (,) is fixed to substantially a central portion of the frame member (,).
