Description of the Invention: [Technical Field] The present invention relates to a light guide plate and a backlight module having the same. [Prior Art] Since the liquid crystal of the liquid crystal display panel itself has no illuminating property, in order to achieve the display effect, a liquid crystal display device, such as a backlight module, needs to be provided to the liquid crystal display panel, and the function thereof is to supply the liquid crystal display panel with sufficient brightness and uniform distribution. Surface light source. The backlight module of the prior art is mainly composed of a light source, a light guide plate, a reflection plate, a diffusion plate and a seesaw. The light source can be disposed on the light guide plate - side or on two opposite sides of the twisted tow. The stencil is to guide the beam transmission direction so that the beam is emitted from the light exit surface (4) of the light guide plate. The reflector is disposed opposite to the bottom surface of the light guide plate, and the light beam emitted by the (four) light guide reducing surface is again reflected into the light guide plate to improve the utilization of the light beam. The diffuser and the fascia are in contact with each other, and the light beam emitted from the light guide plate is more distributed, thereby improving the brightness and uniformity of the liquid crystal display. Moreover, because of the low operating voltage, high luminous intensity, fast response, and long life, the optical diode has its dominance machine, p personal digital assistant, and the back of the display. However, the light of the light-emitting diode has a strong optical directivity, that is, the emitted light has a certain divergent angle sound, and when it directly hits the light guide plate of the backlight module, the optical dark area is easily appeared on the side of the light guide plate. And the position of the light-emitting diode is easy to appear light 200827861 column 'not easy to obtain better light uniformity. • , , 5 Qing See items 1 and 2, *Do not use the T-plane diagram and stereo view of the prior art backlight module.

The light source 12 is disposed on the light incident surface 131 of the light panel 13. The light source 12 is a plurality of light emitting diodes. The light beam emitted from the plurality of light emitting diodes enters the light guide plate 13 through the light incident surface 131 of the light guide plate 13 and is guided. Reflection occurs in the light plate 13. The light guide plate 13 guides the light source 12 to emit a light beam and converts it into planar light which is emitted from the light exit surface 132 of the light guide plate 13. However, since the emitted light of the light-emitting diode has a certain divergence angle, the optical dark area 15 and the light column 16 appear on the side of the light-emitting surface 13 of the light guide plate 13, and the optical dark area 15 is mainly distributed in two adjacent light-emitting diodes. The position of the light column 10 is opposite to the position of the light guide plate 13 facing the light emitting diode, which affects the light uniformity of the backlight module 1 . _ In view of this, it is necessary to provide a light guide plate that allows light to be uniformly emitted, and a backlight module with uniform luminance.
