The present invention relates to a prism film including a structure layer whereby a first pattern unit including a plurality of patterns with a triangular cross-section having a height of H_1 and a base of W_1 alternates with a second pattern including a single pattern with a triangular cross-section having a curvature at its apex; and a height of H_2, and a base of W_2. Here, H_2 is greater than H_1 and W_2 is greater than W_1. Accordingly, when many of these prism films are piled up or when different types of optical films are piled up on the prism film, scratches are prevented from being occurred due to the structure layer, and excellent luminance properties are provided. |
