The present invention relates to an optical sheet and, more specifically, to the optical sheet comprising a threshold pattern. According to the optical sheet, a product forms the threshold pattern higher than the height of a main pattern at both edge parts by an imprint method. The threshold pattern on an initial metal mold adheres to the soft optical sheet arranged on an uneven part when the threshold pattern is wound as having the uneven part on an upper part, and thus a part of the uneven part is combined to the soft optical sheet. |
