Abstract
Official abstract text for this publication.
A backlight module includes a back frame, a light guide plate disposed in the back frame, a plurality of semiconductor light sources, a plurality of light source circuit boards, and a plurality of attachment members. Part of each of the light source circuit boards is disposed between the back frame and the light guide plate, and the other part of each of the light source circuit boards is exposed outside the side edge of the light guide plate, and each of the semiconductor light sources is disposed on the light source circuit boards which are exposed outside the side edge of the light guide plate. The number of the light source circuit boards, the semiconductor light sources, and the attachment members are all at least two. Besides, an LCD device including the backlight module and a manufacturing method for the backlight module are also disclosed.
