    摘要： The photoacid generator according to the present invention is represented by the general formula (1): wherein R1 and R2 are respectively H, OH or alkyl or alkoxy group of C1-5 and are the same or different, n is an integer from 1 to 3, and Ar1 is a naphthalene unit. The photosensitive resin used in a composition of the invention is represented by the general formula (2): wherein X is a tetravalent aromatic or aliphatic organic radical, Y is a bivalent aromatic or aliphatic organic radical, and R3 and R4 independently are H or a monovalent aliphatic organic protecting group removable by acid.

    摘要： An apparatus for fixing an optical film used in a back light to an outer frame of the back light. In the back light, a protrusion protrudes from a frame rim of the outer frame. A film extension extends from one side edge of the optical film and is placed on the surface of the frame rim near the protrusion. A clip is provided with a hole for inserting the protrusion to be mounted onto the frame rim such that the protrusion is inserted into the hole, thereby fixing the film extension of the optical film onto the frame rim.
