Abstract:
The present disclosure provides a reflective polarizer module characterized by comprising: a first light collecting sheet including a first structuring pattern having a first unit light collector, the cross-sectional area of which is reduced progressively upward, which is disposed continuously in a repetitive manner, and collecting a light transmitted from below; a reflective polarizer sheet disposed in a stacked configuration on the top of the first light collecting sheet, and selectively transmitting the light by having a plurality of stacked layers having mutually different refractive indices; and a light recycling improving sheet disposed at the bottom of the reflective polarizer sheet, and randomly changing the polarized direction of the light which is not transmitted through the reflective polarizer sheet but is reflected downward.
