Light, and optical diaphragm 22 includes the perforation 224 of corresponding through-hole 114, framework 12, which extends to hold, to be connect in perforation 224.Reflection diaphragm 23
It is arranged under the second face 112, the aperture 231 comprising corresponding through-hole 114, framework 12, which extends to hold, to be connect in aperture 231.
Because backlight module 2 application any of the above-described embodiment light conducting plate structure 1, backlight module 2 when light source 21 is shinny,
The phenomenon that brightness uniformity can be presented in backlight module 2.
Referring to Fig. 6, the decomposition diagram of the embodiment for display device 3 of the invention.Display device 3 includes shell
31, above-mentioned backlight module 2 and liquid crystal display panel 32.Display device 3 is, for example, flat screens.
Shell 31 has accommodating space 311 and is connected to the window 312 of accommodating space 311.The setting of backlight module 2 is accommodating
Space 311, and the first face 111 is towards window 312.The setting of liquid crystal display panel 32 is in accommodating space 311 and covering window 312.Liquid
Crystal panel 32 includes the hole 321 of corresponding framework 12, and framework 12 is held and connect in hole 321 through perforation 224.
There is above-mentioned light conducting plate structure 1, therefore the first surface 12a and second surface 12b of framework 12 inside display device 3
Light reflectivity it is different, adjustable framework 12 holds the brightness for connecing region with ontology 11, makes the picture of display device 3 that brightness be presented equal
Even phenomenon.
In this embodiment, display device 3 also includes camera lens 322, and framework 12 also includes hole 129, and the setting of camera lens 322 exists
