Claim 0:
1. A side-type backlight module, comprising a light guide plate and a reverse prism sheet that are stacked, wherein
the reverse prism sheet includes a first prism, a surface of the first prism proximate to the light guide plate includes a plurality of prism structures substantially parallel to each other, each prism structure protrudes toward a direction approaching the light guide plate; and
a surface of the light guide plate proximate to the reverse prism sheet includes a plurality of strip-shaped microstructures substantially parallel to each other, each strip-shaped microstructure protrudes toward a direction approaching the reverse prism sheet, wherein
an extending direction of the prism structure crosses an extending direction of the strip-shaped microstructure,
wherein the reverse prism sheet further includes a second prism or an optical film that is disposed on a surface of the first prism away from the light guide plate; the second prism or the optical film is obtained by haze treatment, and a surface of the second prism or the optical film away from the first prism is a haze surface.
