Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical thin film and a back light module using the same. SOLUTION: The optical thin film and the back light module using the same are provided with bar-shaped light conductors on one face of the optical thin film. A part of the light conductors is linear light conductors while another part is continuously curved light conductors. A light source passing through the optical thin film converges by receiving refraction of the bar-shaped light conductors, and thereafter its light flux has no linear regularity on the entire face. When the optical thin film is applied to the back light module, when the light source output therefrom is made incident on a liquid crystal panel, there is no diffraction of the light source, thus preventing formation of interference fringes.
