Optical sheet for TFT-LCD back light unit and liquid crystal display having the optical sheet
The present invention relates to an optical sheet for a backlight unit of a TFT-LCD and a TFT-LCD including the same. The optical sheet of the present invention includes a transparent base sheet, and a light diffusion layer in which a diffusion pattern comprised of a plurality of protrusions is formed on the transparent base sheet. The diffusion pattern satisfies an aspect ratio of 0.8 or more, the aspect ratio being a ratio of a radius (l) of a unit body portion of the protrusion, which is formed on the transparent base sheet, to a thickness (d) of the protrusion.
