Diffusion plate, backlight source and display

The invention discloses a diffusion plate, a backlight source and a display, the diffusion plate comprises a light surface for light incidence, the light surface is provided with at least one special-shaped part, the special-shaped part is a bulge on the light surface of the diffusion plate, and the bulge is used for diffusing light irradiated to the special-shaped part. It can be seen that the convex special-shaped part is arranged on the light surface of the diffusion plate, so that light irradiated by the light-emitting device on the special-shaped part of the diffusion plate is better diffused, the uniformity of an existing diffusion plate is improved in a low-cost mode, and the diffusion plate low in cost and high in uniformity is obtained; therefore, the backlight effect of the backlight device using the diffuser is more uniform in transition, and a backlight source with a better effect is obtained. 本发明公开一种扩散板、背光光源和显示器，所述扩散板包括用于光线入射的光面，所述光面具有至少一个的异形处，所述异形处为所述扩散板的光面上的凸起，所述凸起用于使照射到异形处的光线扩散。可以看出，本发明通过在扩散板光
