Abstract

The backlight module includes a light guide plate, a light source, and a reflection cover for light source. The light guide plate includes a light entering face, a light coming out face conterminous to the light entering face, and bottom face setup opposite to the light coming out face. The reflection cover and the light entering face of the light guide plate form a space for housing the light source. The reflection cover includes a top part and a base part setup oppositely. The top part bunts the light coming out face of the light guide plate, and the base part of the reflection cover is near to the bottom face of the light guide plate. The top part includes a tail end, and the base part includes a tail end. The end of the top part is more far from the light entering face than the tail end of the base part from the light entering face. The backlight module is easy to be assembled. The invention also discloses a liquid crystal display of using the backlight module.

Description

【Technical field】 [0001] The invention relates to a backlight module and a liquid crystal display using the backlight module. 【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. [0003] A prior art liquid crystal display is shown in FIG. 1 . The liquid crystal display 1 includes a front case 11 , a plastic frame 13 , a liquid crystal display panel 17 , a backlight module 19 and a rear case (not shown). The front case 11 and the rear case are combined to form a storage space for accommodating the plastic frame 13 , the liquid crystal display panel 17 and the backlight module 19 . And the liquid crystal display panel 17 is stacked with the backlight module 19 . [0004] The front shell 11 includes a front edge panel 111 and a side edge panel 113 which are perpendicular ...
