Abstract: A display device including a backlight unit; and an image forming unit configured to transmit or block light emitted from the backlight unit to create an image, wherein the backlight unit includes a light source, a reflector sheet configured to absorb light having a predetermined wavelength range among light emitted from the light source, and to reflect non-absorbed light, and an optical sheet configured to absorb light having the predetermined wavelength range among the light emitted from the light source, and to transmit non-absorbed light.

Abstract: A display apparatus may include a back light unit including a light source and a selective light absorption sheet configured to absorb light of a predetermined wavelength range among light emitted from the light source and an image forming unit configured to transmit or block light emitted from the back light unit to form an image. The selective light absorption sheet may include a selective light absorption film configured to absorb light of a predetermined wavelength range among light emitted from the light source, at least one light blocking film configured to absorb at least one of UV light and IR light, and at least one barrier film configured to block at least one of oxygen and moisture.

Abstract: Disclosed herein are a reflecting plate, a backlight unit, and a display device using the backlight unit, and the display device includes one or more light sources; a reflecting plate to which light radiated from the one or more light sources is incident and having a reflecting surface reflecting the incident light; one or more selective light absorbing parts disposed on the reflecting surface and configured to selectively absorb a portion of the incident light; and a quantum dot sheet into which at least one of light emitted without being absorbed by the selective light absorbing part and light radiated from the light source is incident.
