A reflector has a transparent film, an adhesive layer disposed on one surface
of
the transparent film, a groove structure provided on the other surface of the transparent
film, the groove structure having a plurality of grooves including optical path
changing slopes aligned in a substantially constant direction at an inclination
angle in a range of from 35 to 48 degrees with respect to a plane of the transparent
film, a transparent cover film formed so as to cover an outer surface of the groove
structure, and a light diffusing type reflection layer disposed on an outer surface
of the cover film. A lighting-external light double mode liquid-crystal display
device comprising the above reflector and a transmission type liquid-crystal panel,
wherein the reflector is bonded to aback side (opposite to a viewing side) of the
