The backlight module includes a frame, a fixed structure and at least one optical film. The fixed structure includes a fixed part and a connected part connects to the surface and the fixed part. The width of the fixed part is substantially greater than the width of the connected part. The at least one optical film includes an accommodated part comprising a first portion and a second portion adjoins to the first portion. The width of the first portion is substantially greater than or substantially equal to the fixed part, and the width of the second portion is substantially greater than or substantially equal to the width of the connected part.
RELATED APPLICATIONS This application claims the benefits of Taiwan Application No. 96101652, filed Jan. 16, 2007, the contents of which are herein incorporated by reference in its.
SUMMARY Therefore, it is provided by the present invention an optical film that comprises a body and an accommodation part. The accommodated part is connected to the body, and includes a first portion and a second portion adjoining the first portion. The width of the first portion is substantially greater than the width of the second portion.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The following description is of the best-contemplated mode of carrying out the present invention. This description is made for the purpose of illustrating the general principles of the present invention and should not be taken in a limiting concept. The scope of the present invention is best determined by reference to the appended claims.
Referring to FIG. 4 illustrates a diagram of a first embodiment of the present invention. There is a fixed structure 202 on a top surface at a side of the frame 200. The fixed structure 202 includes a fixed part 202A and a connected part 202B connecting the surface at the side of the frame 200 and is the fixed part 202A. Preferred, the width of the fixed part 202A is substantially greater than the width of the connected part 202B. The connected part 202B of the fixed structure 202 is preferably but not limited to couple to a substantially center region of the fixed part 202A. For example, the connected part 202B can couple to a place is substantially strayed from the center region of the fixed part 202A, an end is substantially away from the center region of the fixed part 202A (not shown), or can be located at other position. A shape of the fixed part 202A in a top view may preferably but not necessarily be an substantially ellipse. The shape of the fixed part 202A in a top view may otherwise be a shape of �substantially C�, a substantially round, a substantially triangle, a substantially polygon, or other shapes. A connected part 202B may be a column or pillar, in where a top view of the connected part 202B may preferably but not necessarily include a substantially semi-ellipse or a substantially semi-circle. The shape of the connected part 202B in a top view may otherwise include a substantially triangle, a substantially trapezoidal, a substantially polygon, or other shapes. The surface of the side of the frame 200, in where the fixed structure 202 is installed at the side, is preferably substantially scraggy. The fixed structure 202 is preferably located in an indentation part 210 of the surface of the frame 200, or may be on a border of an indentation part and a protrusion part of the frame 200, in a protrusion part, or at other location of the frame 200. The frame 200 includes at least one protruding edge 212 located at another side of the frame 200, in where said side is away from the fixed structure 202. In other words, the protruding edges are located at a side of an accommodated part away from the frame. The at least one protruding edge 212, is capable of providing an obstruction for an optical film 204 when installing the optical film 204 on the frame 200. The indentation part 210 is preferably but not necessarily formed by two adjacent protruding edges 212, such that the fixed structure 202 is located between the two protruding edges 212. However, the indentation part 210 can alternately be next to only one protruding edge 212.
