A liquid crystal display unit is characterized by comprising a liquid crystal display panel, a back-light instrument for outputting light to the liquid crystal display panel, and a scattering-anisotropic optical instrument disposed on that side of the liquid crystal display panel which is opposite to the back-light instrument. The scattering-anisotropic optical instrument is so formed that the scattering intensity of light vertically entering the display screen of the liquid crystal panel is maximized. Therefore, the scattering-anisotropic optical instrument can scatter light vertically entering the display screen of the liquid crystal panel to allow a viewer to view a display screen from a wide range of viewing angles. In addition, because the unit does not scatter light entering obliquely, rather than vertically, a display screen but lets the light pass as it is, whitish appearance as is seen in an oblique-direction observation can be prevented. Therefore, whitish appearance can be prevented even if the back-light instrument does not output perfectly parallel light.
