PURPOSE: A system for inspecting defects of an optical film is provided to improve the degree of finishing of optical product film by respectively inspecting or complementarily inspecting 3D failure with first and second inspecting devices. CONSTITUTION: A system for inspecting defects of an optical film(10) comprises a first inspection device(100) and a second inspection device(200). The system inspects the defects on a surface of the optical film which travels at a preset speed. The first inspection device includes a first photographing unit for inspecting first optical defects of the optical film. The second inspection device includes a second photographing unit for inspecting first optical defects and second optical defects of the other optical film. The optical film is a patterned retard film where L and R patterns having different optical shafts are formed. The first inspection device includes a first photographing unit(140) for inspecting first optical defects of the optical film. The second inspection device includes a second photographing unit for inspecting first optical defects and second optical defects of the other optical film. The optical film is a patterned retard film where L and R patterns having different optical shafts are formed. |
