The present invention discloses a side-light type backlight module with local heat-dissipation enhancement. The backlight module is provided with a local heat-dissipation enhancement region on a portion of the back plate close to at least one light input side edge, and a surface of the local heat-dissipation enhancement region has a thermal-conductivity enhancement coating and a three-dimensional heat-dissipation profile, so that the temperature can be rapidly distributed to an even degree and lowered down, and the heat exchange area can be increased. Thus, the side-light type backlight module with local heat-dissipation enhancement of the present invention can efficiently prevent from affecting the chromaticity and brightness of a light emitting device due to the high temperature, so as to improve the uniformity of the chromaticity and brightness of an entire liquid crystal display (LCD) module and enhance the light extraction efficiency thereof.
