    Abstract: A backlight device includes a prism film having a top face on a display panel side and a bottom face opposing the top face, and a reflector plate having a reflection face opposing the bottom face. A prism-like pattern is formed on the top face of the prism film and a scattering pattern is formed on the reflection face of the reflector plate. When a first normal line axis of a slope forming the prism-like pattern and a second normal line axis of one slope forming the scattering pattern are projected on an imaginary plane parallel to the display panel, the projected first and second normal line axes form an acute angle.

    Abstract: A display device according to one aspect of the present invention includes: a display unit configured to have display information and emits visible light having a continuous spectrum; an infrared cut-off part configured to transmit the visible light from the display unit and to reduce the amount of infrared light striking the display unit; and a reflecting part configured to reflect the visible light having passed through the infrared cut-off part. The infrared cut-off part includes a first polymer film and a second polymer film, the first polymer film includes an infrared cut-off layer configured to reduce infrared light transmission, and the second polymer film includes a high-retardation polyester film and is disposed between the first polymer film and the display unit.
