Description

【Technical field】 [0001] The invention relates to a backlight module and a manufacturing method thereof. 【Background technique】 [0002] Due to the advantages of lightness, thinness, and low power consumption, liquid crystal display devices are widely used in modern information equipment such as notebook computers, mobile phones, and personal digital assistants. Since the liquid crystal itself does not have light-emitting properties, it is necessary to provide a backlight module for it to realize the display function. [0003] Please refer to FIG. 1 , a backlight module 1 of the prior art includes: a metal back plate 11 having a side 111 and an inner bottom surface 113 , a plastic frame 12 including a side wall 121 , a reflector 13 located above the inner bottom surface 113 , The light guide plate 14 above the reflection plate 13 , the diffuser plate 15 above the light guide plate 14 , and the light source 16 adjacent to one end of the light guide plate 14 . The metal back...
