OPTICAL ADJUSTING MEMBER AND ILLUMINATION DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an optical adjusting member capable of solving the problems of color separation and insufficient luminance and obtaining reduction in the thickness and the cost of the illumination device and the liquid crystal display device.

SOLUTION: An optical adjusting member includes a base member having optical transparency and a plurality of linear members provided on the base member and having optical transparency. A section of the linear member orthogonal to the lengthwise direction of the linear member includes a triangular first sectional part defined by first to third sides and an approximately triangular second sectional part. The second sectional part has a smaller area than that of the first sectional part and defined by fourth to sixth sides. The first side of the first sectional part is in contact with the surface of the base member in parallel. The second sectional part is formed on the second side of the first sectional part, and the fourth side of the second sectional part is in contact with the second side of the first sectional part in parallel.
