Claim Text:
1. A display screen, comprising a first substrate, a second substrate and a liquid crystal layer arranged between the first substrate and the second substrate; wherein the first substrate comprises a base substrate, an optical module arranged on the base substrate, and a plurality of pixel units directly arranged on the optical module; the second substrate comprises an array substrate; wherein the optical module comprises: a light guide plate arranged on the base substrate; a prism film layer arranged on the light guide plate, wherein the prism film layer is provided with a ribbing; and a diffusing film layer arranged on the prism film layer; wherein the light guide plate comprises: a reflection layer formed on the base substrate; an indium tin oxide (ITO) layer formed on the reflection layer, wherein an etching hole is formed at a position of a lattice point in the ITO layer; and a light guide film layer coated on the ITO layer, wherein a lattice structure is formed by the light guide film layer in the etching hole of the ITO layer, and the light guide film layer has a flat surface.
