Abstract
Official abstract text for this publication.
The invention relates to a backlight module and an LCD device comprising the backlight module. The backlight module includes a backplane, and an optical film arranged on the backplane; the optical film is provided with a convex lug for positioning, the convex lug is provided with a root and an expanded part which is outwards extended, and the width of the expanded part is more than that of the root; the side wall of the backplane is provided with first protrusion(s) which is provided with an opening, the root of the convex lug of the optical film is contained in the opening, the side wall of the backplane is further provided with second protrusion(s) which is provided with an extension part, and the expanded part of the convex lug of the optical film is contained below the extension part of the second protrusion. In the invention, the second protrusion is arranged on the backplane, and the extension part of the second protrusion can prevent the convex lug of the optical film from moving in the direction perpendicular to the plane of the optical film. The cost for arranging the second protrusion is low, and the installation means of the optical film has the advantages of simplicity, time saving, and labor saving.
