PURPOSE: A prism sheet is provided to improve scratch resistance and a yellow band or rainbow phenomenon. CONSTITUTION: A structural layer(20) is formed on one side of a base material layer(10) A plurality of stereoscopic structures are linearly or non-linearly arranged. A back coating layer is formed on the other side of the base material layer and disperses particles. A static friction coefficient between the structural layer and the back coating layer is 0.2 to 0.3. |
