A reflection type liquid-crystal display which is excellent in contrast when viewed with or without illumination and also in display brightness and in which displayed images viewed through a light conductive plate are less apt to be disturbed, i.e., excellent in clearness, and are less apt to have a decrease in perceptibility caused by moire phenomenon; and to develop a light conductive plate and a surface light source device with each of which the liquid-crystal display can be fabricated. A light conductive plate having, formed on the upper surface (11) thereof, a light-emitting means which serves to deflect incident light from an incidence-side edge (13) of the plate to emit the light through the lower surface (12) of the plate and further having, at least on the lower surface thereof, an antireflection layer (2) which enables incident light from the lower surface of the plate to pass through the upper surface of the plate; a surface light source device comprising the light conductive plate described above and a light source disposed by the incidence-side edge thereof; and a reflection type liquid-crystal display comprising the surface light source device described above and, disposed on the lower side thereof, a liquid-crystal cell having a reflecting layer. The antireflection layer disposed on the lower surface inhibits the upper surface from emitting the leakage light which is superposed on displayed images to cause white blurring and a decrease in contrast, whereby satisfactory perceptibility is attained regardless of whether the display is in an illuminated or unilluminated state.
