Abstract:
A liquid crystal display device, comprising:a liquid crystal cell holding nematic liquid crystal with twisted alignment between a first substrate having a first electrode and a second substrate having a second electrode; an upper polarizer provided outside the second substrate at a visible side of said liquid crystal cell; a lower polarizer and a scattering layer provided outside the first substrate at a side opposite to the visible side of said liquid crystal cell; a light guide film of side light type provided outside said lower polarizer and said light scattering layer; and a reflector provided outside said light guide film, wherein said light guide film is a light guide film with a light scattering property in which particles with a light scattering property are mixed; each of said scattering layer and said light guide film with the light scattering property has a property of scattering incident light while substantially maintaining a polarizing state thereof, and wherein a reflection display on a visible side is performed by reflecting light incident from the visible side at a reflection layer provided outside said light guide film, and a transmission display on the visible side is performed with incident light from said light guide film.
