An optical sheet (30), according to the present invention, includes a support sheet (310); and a prism sheet (320) which is formed on the support sheet (310) and includes a plurality of prism patterns (330). There is a difference of a predetermined value between the pitch of a reference prism (PN) among the prism patterns (330) and the pitch of the prism pattern (PN-1, PN+1) adjacent the reference prism (PN). An embodiment according to the present invention may provide an optical sheet which has prism patterns with non-uniform pitches to prevent the generation of Moire effect, and a liquid crystal display device having the same. |
