ABSTRACT:
A reflector is provided in a reflective or transmissive liquid crystal display device. In the reflector, when light is incident on the reflector in a first direction, a reflection characteristic profile of light reflected therefrom shows a reflectance distribution which is asymmetric with respect to a specular reflection angle of the incident light and shows a non-Gaussian distribution in which a maximum value of reflectance is within a reflection angle range smaller than the specular reflection angle of the incident light. In addition, when light is incident on the reflector in a second direction perpendicular to the first direction, a reflection characteristic profile of light reflected therefrom shows the non-Gaussian distribution, similar to the case in which the light is incident on the reflector in the first direction.
