    Abstract: A stacking-type optical sheet module includes an upper optical sheet having a first structural pattern with first unit light-condensing bodies successively repeated and cross-sectional areas gradually decreasing towards the top. A lower optical sheet has a second structural pattern and is below the upper optical sheet in a stack. Second and third unit light-condensing bodies are successively disposed in the second structural pattern. The second unit bodies have a gradually decreasing cross-sectional area toward the top and are joined with the upper optical sheet, and the third unit bodies have a gradually decreasing cross-sectional area toward the top, a vertical distance from a lowest to a highest portion thereof being relatively shorter than a corresponding vertical distance of the second unit bodies. A vertical angle of the highest portion of the second unit bodies is relatively smaller than a vertical angle of the highest portion of the third unit bodies.
