Abstract

The invention relates to a light guide plate for the direct-type backlight module and, more particularly, to an optical sheet body providing light guide function for the cold cathode fluorescent lamps of the direct-type backlight module. The optical sheet body comprises at least a light emitting face and a light ejecting face on the top face and a light ejecting pattern face formed on the light ejecting face so as to dispose the light guide plate between or above the cold cathode fluorescent lamps, thereby enabling to have uniform distribution and increase luminance for the light passing therethrough, so as to solve the problem of the bright filaments and the uneven light of the tubes for the direct-type backlight module. In addition, at least one tube holder can be installed in the light guide plate to receive the cold cathode fluorescent lamp, thereby providing reinforced protection for longer tubes used for large-sized liquid crystal panels and shortening the space between the panel and the backlight module so as to thin out large-sized liquid crystal panels.
