<p>The present invention relates to a condensing type optical sheet and, more specifically, to a condensing type optical sheet to improve color uniformity and to minimize a decrease in brightness through the curvature of the cross-sectional slope of a three-dimensional structure on the structural layer of the condensing type optical sheet. According to the present invention, the condensing type optical sheet comprises: a base material layer; and the structural layer which is formed on one or both sides of the base material and on which a plurality of three-dimensional structures are arranged. The three-dimensional structure of the structural layer has a streamlined longitudinal section and includes a slope part extending in both directions on the basis of a peak point.</p> |
