ABSTRACT:
A reflective type or transmissive and reflective type LCD device enhances reflectivity of light in a plurality of directions. The LCD device includes a first substrate having a plurality of pixels, TFTs formed on the first substrate, an insulating layer, a reflective electrode, a second substrate opposite to the first substrate, and liquid crystal layer interposed between the first and second substrates. The reflective electrode includes a plurality of embossing members arranged repeatedly thereon to form an embossing pattern. The embossing members have inclined faces inclined asymmetrically in a plurality of directions, for example in a first, second, third and fourth directions. A viewing angle of the LCD device may be broaden in various directions regardless of an incident angle of light incident into the LCD device, and the reflectivity of the LCD device may be increased, thereby enhancing luminance of the LCD device.
