Abstract

The present invention provides an optical film assembly mounting structure, which includes: a first mold frame ( 6 ), a second mold frame ( 8 ) arranged on the first mold frame ( 6 ), and an optical film assembly ( 9 ) arranged between the first and second mold frame ( 6, 8 ). The first mold frame ( 6 ) carries the optical film assembly ( 9 ) thereon and the second mold frame ( 8 ) is positioned on and presses down the optical film assembly ( 9 ) so as to achieve secure mounting of the optical film assembly ( 9 ). The first mold frame ( 6 ) includes an inclined first upper surface ( 61 ). The second mold frame ( 8 ) includes a first bottom surface ( 81 ) and a second bottom surface ( 83 ) connected to the first bottom surface and having an inclination angle identical to that of the first upper surface ( 61 ). The optical film assembly ( 9 ) is positioned on the first upper surface ( 61 ) and the first and second bottom surfaces ( 81, 83 ) are positioned on and press down the optical film assembly ( 9 ).
