Provided are an optical sheet which can widen field of view of a liquid crystal display device by increasing light distribution characteristic, and the liquid crystal display device including the same. The optical sheet comprises: a first condensing film in which a first prism pattern having a first refractive index is formed; and a second condensing film in which a second prism pattern having a second refractive index is formed to correspond to the first prism pattern and be overlapped, wherein the second prism pattern is formed as at least two prisms having different angles of corresponding apexes form a group and are repeated. |
