Backlight module and liquid crystal display device

摘要

The present invention discloses a backlight module, which includes: a backplane, which has a sidewall; a light guide plate, which is carried on the backplane and includes a light incidence end section, a light exit surface, and a bottom surface opposite to the light exit surface; a light source, which is mounted on the sidewall and adjacent to the light incidence end section; an intermediate frame, which is set on and covers the light guide plate and the light source; a first retention slot, which is formed in the light incidence end section and has an opening facing the intermediate frame; a second retention slot, which is formed in the light incidence end section and close to the first retention slot and has an opening facing the backplane; a first quantum dot strip, which is received in the first retention slot; and a second quantum dot strip, which is received in the second retention slot. The present invention also discloses a liquid crystal display device. The present invention provides an arrangement including quantum dot strips arranged in the light incidence end section in a top-down staggering manner, where the manner of fixing is simple and light emitting from the light source is prevented from directly entering the light guide plate so as to improve the taste of the color of the backlighting.
