Abstract

A direct type backlight module for a liquid crystal display includes a frame having several sidewalls, at least an optical sheet and a plurality of light sources. At least a fixing portion is positioned at an upper surface of at least two opposite sidewalls of the frame. Each fixing portion has a spring sheet disposed in the bottom thereof. The optical sheet has a number of positioning opens according to the spring sheets that can be inserted into the positioning opens for fixing the optical sheet to the frame. The light sources are disposed under the optical sheet. The optical sheet of the direct type backlight module can be better fixed to the frame without deflection problem.
