Description of the invention: [Technical field to which the invention pertains] The present invention relates to a backlight module and a liquid crystal display device using the same. [Prior Art] A liquid crystal display device is mainly used for various information; a human computer, a liquid crystal television, a mobile phone, a video camera such as a module? ?? : species: skill 2 = "two light = the light source 11 is a light-emitting diode, i ii into the first face: 12 center: below the line: in the light-guided surface of the light guide plate 1G,, produce 〇χβ〇χ 1. Exercising, passing through the light-incident surface 12 into the guide, the sub-reflection is reflected in it, and finally emitted by the light-emitting surface 13. In the case of iron, the range of illumination of the light-emitting diode u is limited to Angle, into the 匕, the light of the plate 10 soil is not uniform, usually the light-emitting diode u center line at the center of the light gi face 11 towel * line less light, the light plate 10 into the upper and lower people radiance (four), Therefore, in view of the above, it is necessary to provide a backlight module with uniform light emission. [ SUMMARY OF THE INVENTION] It is an object of the present invention to provide a backlight module with uniform light emission. The backlight module of the present invention comprises a light guide plate and a light emitting diode, the light guide plate includes a light incident surface, and the light emitting diode is disposed opposite to the light incident surface, wherein the light emitting diode is disposed The center line of the light-emitting diode is the same as the center line of the light-incident surface of the light guide plate The liquid crystal display device of the present invention comprises a liquid crystal display screen and a light touch with respect to the liquid crystal 1254822. The light module comprises a light guide plate and a light-emitting two-light plate comprising a human light region. The diode is disposed relative to the human light region, and the center line of the turtle light dipole is in the same plane as the center line of the light entrance region of the light guide plate, and the center line of the light surface of the light guide plate of the present invention is Light-emitting two-pole ίί and think: ιί面' makes the light emitted from the light-emitting diode evenly enter the light guide plate and the uniformity of the light output of the prismatic light module. [Comprehensive mode] Figure 2. Two 9® = back of the present invention The plane of the light-emitting diodes and the light-emitting diodes 21 and the light-emitting diodes 21, the light-emitting diodes 21 are incident on the light-guiding plate 20 The center line of the surface of the electrode body 21 and the light-incident surface 22 of the light guide plate 2 C = the thickness of the light-emitting diode 21 is smaller than the brightness of the light guide plate 20 ▲ ^ and the V first plate 20 The distance is 1} (1〇-4 meters. Please refer to the third figure, which is a backlight module of the present invention. The backlight module is the first one. The younger one is not thinking about it: the back group 3, including the group = the same 'the difference circuit board 36, the soft circuit, jf 3, which is directly disposed on a flexible board 36 to directly supply power to the light source 31 The y reflective layer 37 is included in the y reflective layer 37. The flexible circuit 37 can reflect the light back to the light guide plate 3. The connection between the two and three is reduced, and the power consumption of the reflective layer is reduced. The fourth embodiment is not intended to be a liquid of the present invention. The liquid crystal display device 4 includes a stereoscopic group 2 of the mode: the light-emitting surface 23 of the backlight module 2 is opposite to the center line of the light-emitting diode. : First, J, and the light plate of the light plate enters the light surface to enter the light guide plate, thereby improving the light input from the group of electrodes. 14 ? 1254822 y according to different design requirements, the backlight module can also be increased or decreased. Further, it includes a ruthenium sheet, a diffusion sheet, a reflection sheet, and a polarizer. 3 ‘The above description, the invention has indeed met the requirements of the invention patent, and the special request is made according to law. However, the above description is only a preferred embodiment of the present invention, and the Abb of the present invention is not limited to the above-described embodiments, and those skilled in the art can make equivalent modifications or changes according to the spirit of the present invention. , should be covered in the following patent application Fan 1 Army 1.
