Abstract
A lighting device includes a plurality of light sources, a light diffusion plate, a sheet-like optical member, and a partition. The light diffusion plate is arranged opposite the light sources. The light diffusion plate diffuses light from the light sources. The optical member is disposed between the light diffusion plate and the light sources. The optical member includes a transmitting part that transmits the light emitted from the light sources and a reflecting part that reflects the light emitted from the light sources. The partition is arranged between adjacent light sources. The optical member is held by a support portion that is integrally provided to the partition and protrudes from an end portion of the partition toward the light diffusion plate.
Claims20
A lighting device comprising:
- a plurality of light sources;
- a light diffusion plate arranged opposite the light sources, the light diffusion plate diffusing light from the light sources;
- a sheet-like optical member disposed between the light diffusion plate and the light sources, the optical member including a transmitting part that transmits the light emitted from the light sources and a reflecting part that reflects the light emitted from the light sources;
- and
- a partition wall arranged between adjacent light sources, the partition wall entirely surrounding each of the light sources to independently partition the light sources relative to each other,
- the optical member being disposed on a top surface of the partition wall and held by a support portion that is integrally provided to the partition wall and extends from the top surface of the partition wall toward the light diffusion plate.
A display device comprising:
- a display panel;
- and
- a backlight disposed rearward of the display panel, the backlight emitting light to the display panel, the backlight including
- a plurality of light sources,
- a light diffusion plate that is arranged opposite the light sources, the light diffusion plate diffusing light from the light sources,
- a sheet-like optical member that is disposed between the light diffusion plate and the light sources, the optical member including a transmitting part that transmits the light emitted from the light sources and a reflecting part that reflects the light emitted from the light sources, and
- a partition wall that is arranged between adjacent light sources, the partition wall entirely surrounding each of the light sources to independently partition the light sources relative to each other,
- the optical member being disposed on a top surface of the partition wall and held by a support portion that is integrally provided to the partition wall and extends from the top surface of the partition wall toward the light diffusion plate.
