Double-sided adhesive is set, while the stability that diffusion sheet 3 is connect with backlight luminous board 2 can also be improved.
When the first sub- extension 321 is threadedly coupled with backlight luminous board 2, the first sub- extension 321 is towards backlight luminous board 2
Side is provided with threaded hole, is provided on backlight luminous board 2 and passes through with the one-to-one through-hole of threaded hole, bolt by matching with threaded hole
The connection for realizing backlight luminous board 2 and the first sub- extension 321 is closed, before backlight luminous board 2 is connect with the first sub- extension 321,
The link position of default backlight luminous board 2 and the first sub- extension 321, when preset link position changes, due in mode two
Multiple first sub- extensions 321 form closed cyclic structure, reduce the limitation being changed to link position, improve
The practicability of diffusion sheet 3.
In order to further make the bending degree of backlight luminous board 2 identical as the bending degree of main part 31 of diffusion sheet 3, guarantee
Display device uniform in light emission, in the embodiment of the present invention, extension 32 further includes at least one second sub- extension 322, and described
In the display area for the main part 31 that two sub- extensions 322 are formed in the diffusion sheet 3.
Above-mentioned extension 32 further includes the second sub- extension 322 being arranged in the display area of main part 31, passes through
One sub- extension 321 and the second sub- extension 322 are connect with backlight luminous board 2, make in backlight luminous board 2 with the first sub- extension 321
Join domain be bonded completely with the first sub- extension 321 towards the surface of backlight luminous board 2, in backlight luminous board 2, prolong with the second son
The join domain of extending portion 322 is bonded with the second sub- extension 322 towards the surface of backlight luminous board 2 completely, thus to backlight luminous board 2
Bending degree further limit so that the bending degree of backlight luminous board 2 is identical as the bending degree of main part 31.
Since the second sub- extension 322 is arranged in the display area of main part 31, in order to avoid the second sub- extension 322
Setting influence the display effect of display device, in the main part 31 of diffusion sheet 3, be formed with the region of the second sub- extension 322
Astigmatism particle concentration P1, less than the concentration P2 of the astigmatism particle in the region of the not formed second sub- extension 322.
In aforementioned body portion 31, the concentration P1 for being formed with the astigmatism particle in the region of the second sub- extension 322 is less than non-shape
At the concentration P2 of the astigmatism particle in the region of the second sub- extension 322, main part 31 is formed with the region of the second sub- extension 322
Astigmatism particle concentration it is lower, can be improved the transmitance of the light in the region, reduce the atomization to light of 3 main part 31 of diffusion sheet
Effect ensure that backlight module 10 to prevent from forming shade at the region that second sub- extension 322 is formed in main part 31
Light-out effect ensure that the light-out effect and picture display effect of display device.
