Abstract:
The present invention provides a diffusion plate and a direct-type backlight module. By disposing the first groove on the light incident side of the second structure layer of the diffusion plate, disposing the second groove or the third protrusions on the light emitting side of the second structure layer, and the refractive index of the first structure layer, the second structure layer and the third structure layer is sequentially increased, the divergence angles of the incident light can be significantly increased, to achieve uniform backlight brightness. The direct-type backlight module of the present application includes the diffusion plate described above. The mura problem can be solved while reducing the number of the LED lamps and the light mixing distance, so as to realize the low cost and slim design of the direct-type backlight module, and are conducive to the use of the direct-type backlight module in the ultra-thin TV field.

Claim (Index 2):
The diffusion plate according to  claim 1 , wherein a hollowed portion of the first groove is a part of an ellipsoid, specifically less than or equal to one-half of the ellipsoid, the ellipsoid is a geometric body surrounded by an ellipse rotating around a long axis of the ellipse, the long axis of the ellipsoid is parallel to the second structural layer, and\n an opening of the first groove is oval, defining a length of a long axis of the opening of the first groove is d1, a distance from a lowest point of the first groove to the opening is h1, and h1<d1.
