摘要： An optical device which maintains luminance characteristics to the greatest extent, improves light-collecting effects, and realizes a wide viewing angle, and a backlight unit and an LCD including the same. The optical device includes a light-transmitting base film. A plurality of convex portions is formed on at least one surface of the base film, and microscopic optical patterns have peaks and valleys, which abut each other, on part of the convex portions. Alternatively, a plurality of third fine optical patterns is formed on at least one surface of the base film. A portion of each third fine optical patterns abutting the base film forms a figure having long and short axes. Each of the third fine optical patterns has a peak with a height that decreases from the center to both ends thereof along the long axis.
