A display unit of the disclosure includes a display panel and a light-distribution adjustment sheet. The light-distribution adjustment sheet is provided on the display panel, and includes a protrusion that protrudes toward the display panel. The protrusion includes a first region including a curved surface, and a second region including a flat surface.

Light-distribution adjustment sheet and display unit

An optical unit includes a ball lens and a light source. The ball lens condenses light and outputs the condensed light. The light source has a light emitting surface and the light source outputs light toward the ball lens. The light emitting surface is located closer to the ball lens than a focal position of the ball lens.

Optical unit, illumination apparatus, display, and optical communication apparatus

A backlight unit of the present disclosure includes: a backlight including a plurality of light-emitting devices that are allowed to emit light at mutually different timings and include a first light-emitting device and a second light-emitting device; and a controller that controls a light emission operation of the backlight to cause the first light-emitting device and the second light-emitting device to emit light with mutually different average light emission intensities in a first sub-frame period of a plurality of sub-frame periods provided corresponding to a frame period.

Backlight system, display apparatus, and light emission control method

There is provided a light-emitting device that exhibits superior luminance contribution rate of a light source while reducing in-plane luminance unevenness despite a simple configuration. The light-emitting device includes: a substrate on which one or more light sources are provided; and a reflective plate placed on the substrate. The reflective plate includes: an opening into which the light source is inserted; a sloped section that is sloped relative to the substrate while surrounding the opening, and has a first thickness; and a top surface section that is coupled to a top end of the sloped section, and has a second thickness. The first thickness is greater than the second thickness.

Light-emitting device, display apparatus, and lighting apparatus

Disclosed herein is a light emitting device, including: a light emitting diode; an sealing resin member having an arrangement face and configured to seal the light emitting diode; and a lens disposed on the arrangement face of the sealing resin member and formed so as to have a circular shape as viewed in the direction of an optical axis of light emitted from the light emitting diode, the lens having a concave portion formed at a central portion in such a manner as to be concave toward the sealing resin member.

Light emitting device, area light source apparatus and image display apparatus

A light emitting device includes a plurality of light emitting diodes, a plurality of sealing resins, and a lens body formed in substantially a shape of a flat plate for guiding the light. The lens body is also disposed in a state of extending over the disposition surface of each sealing resin. The lens body includes a plurality of lens parts and a plurality of light guiding parts for reflecting the light by inside surfaces of the light guiding parts. The plurality of lens parts and the plurality of light guiding parts of the lens body are formed integrally with each other. The lens parts are disposed on the respective disposition surfaces of the sealing resins, and a plurality of light emitting function parts for sending out the light reflected by the inside surfaces of the light guiding parts are formed in the light guiding parts.
