[0032] Example one
[0033] figure 2 It is a top view of the structure of the first embodiment of the present invention, such as figure 2 As shown, the backlight module 200 includes at least one LED light source 201, a reflecting device 205, a rectangular light guide plate 202, a frame 203 and a set of optical films (not shown). The light guide plate 202 has a light incident surface 204, and the reflective surface of the reflection device 205 is disposed opposite to the light incident surface 204 of the light guide plate 202. The LED light source 201 is arranged between the reflection device 205 and the light entrance surface 204 of the light guide plate 202. The light exit surface of the LED light source 201 is inclined toward the light entrance surface 204 of the light guide plate 202 and is arranged at a certain angle b, and the included angle b is greater than 0. ° and less than 90 °.
