1. A liquid crystal display device comprising:

  • a scattering/transparent liquid crystal cell having a liquid crystal layer for controlling incident light in a scattered or transparent state in accordance with an applied electric field; and

    a selective reflector arranged on a side of said liquid crystal layer opposite to a side where observation is performed, and having reflecting characteristics to cause light, which is incident from a direction within a predetermined range of a viewing angle that allows observation of said liquid crystal cell, to reflect in a direction outside the range of the viewing angle on the side where observation is performed;

    wherein said selective reflector comprises a light incident surface that forms linear prisms each of which has first and second slants inclined in opposite directions, and a specular reflection layer formed on both of the first and second slants, the light incident surface having light reflecting characteristics that achieve dark black display.
