Claim:
A LCD display device ( 300 ) comprising: a backlight module ( 200 ); and a LCD display ( 400 ), disposed on top of said backlight module ( 200 ); said backlight module ( 200 ) comprises a substrate ( 4 ), pluralities of optical fibers ( 100 ) closely arranged in parallel on a plane surface of said substrate ( 4 ); and at least one illuminating device ( 3 ), connected to said optical fibers ( 100 ) for providing illumination, said backlighting optical fiber ( 100 ) comprising: an optical fiber ( 1 ) with a recess ( 11 A˜ 11 F) axially disposed along the inner wall; and a reflector ( 2 A˜ 2 F) set into said recess ( 11 A˜ 11 F), said reflector ( 2 A˜ 2 F) includes a reflecting surface ( 21 A˜ 21 F) disposed on the inner side of said reflector ( 2 A˜ 2 F), to reflect the incident light (L) to the opposite direction of said reflector ( 2 A˜ 2 F); the shape of said reflecting surface ( 21 A˜ 21 F) is one of following: a concave surface with curvature less than 180 degree, a convex surface with curvature less than 180 degree, a concave surface with curvature equal to 180 degree, a convex surface with curvature equal to 180 degree, a concave surface with curvature more than 180 degree and a convex surface with curvature more than 180 degree.
