A diffuser-integrated prism sheet is provided, in which diffuser layers are provided on the upper and lower surfaces of the prism sheet and prism-shaped protrusions are formed in the prism sheet. The prism sheet for backlight units includes a lower diffuser layer having a light diffusion structure, a lower layer formed on the lower diffuser layer, a first intermediate layer formed on the lower layer and having prism-shaped protrusions formed parallel to each other, a second intermediate layer formed on the first intermediate layer, an upper layer formed on the second intermediate layer, and an upper diffuser layer formed on the upper layer and having a light diffusion structure, wherein an air layer is formed between the lower surface of the second intermediate layer and the valleys of the prism-shaped protrusions of the first intermediate layer. Also, a method of manufacturing the diffuser-integrated prism sheet is provided.
