Abstract: A diffusion sheet, a backlight module and a liquid crystal module are disclosed. The diffusion sheet comprises a paper fiber layer (1) with surfaces on two sides both disposed with a light-transmissive protection layer (2, 3). The diffusion sheet can well diffuse light passing through the diffusion sheet, and hence improve uniformity of light passing through the diffusion sheet. A paper fiber layer (1) is employed in the diffusion sheet for diffusion, which makes a paper fiber layer (1) be prepared at a low cost and have a small weight, and hence reduce the preparation cost and weight of a diffusion sheet to provided convenience for transfer of a product.
