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. |
