摘要： The present invention provides an integrated optical sheet module where an optical sheet is integrally formed without a diffusion sheet, a condensing sheet and a reflective polarizing sheet thereby reducing the overall thickness and improving the viewing angle, so that a manufacturing process can be simplified and significantly improve the left to right viewing angle while minimizing the brightness drop by forming the first base film having the viewing angle improvement component on the bottom surface with a haze characteristic.

摘要： The present disclosure relates to an optical sheet having improved optical properties and minimized surface spots. According to one aspect of the present disclosure, provided is an optical sheet comprising: a first prism sheet which has a plurality of prisms parallel in a first direction formed on one surface thereof; and a diffusion sheet which is positioned at the surface side into which light of the first prism sheet is incident and has a plurality of protrusions formed on the surface facing the first prism sheet.

摘要： 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.
