    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.
