Abstract
A display apparatus includes a liquid crystal panel; a plurality of light sources configured to emit blue light; a reflective sheet including a plurality of holes through which the plurality of light sources are exposed; a diffuser plate configured to diffuse the light emitted from the plurality of light sources; and an optical sheet configured to improve luminance of the light emitted from the plurality of light sources, wherein at least one of the diffuser plate or the optical sheet includes a plurality of light conversion patches.
Claims19
A display device comprising:
- a liquid crystal panel;
- a plurality of light sources configured to emit blue light;
- a reflective sheet comprising a plurality of holes through which the plurality of light sources are exposed;
- a diffuser plate configured to diffuse the light emitted from the plurality of light sources;
- and
- an optical sheet configured to improve luminance of the light emitted from the plurality of light sources,
