Abstract
The present invention provides a reflective polarizing module for enabling bending reduction, comprising: a reflective polarizing sheet having a cooling surface in which a plurality of stacks having different refractive indices from each other are laminated to selectively transmit light and which is cooled by being in contact with a separate cooling roll in a heated state, and an outer exposed surface which is placed in a stacked form on an upper portion of the cooling surface and is exposed to air to thereby slowly cool, wherein the reflective polarizing sheet has a shrinkage rate of the cooling surface by means of a temperature rise which is relatively higher than the shrinkage rate of the outer exposed surface; and an adhesive layer which is provided to at least any one of the cooling surface or the outer exposed layer to thereby bond a separate optical module and the reflective polarizing sheet, and reduce shrinkage and bending of the reflective polarizing sheet according to a temperature rise due to a shrinkage rate difference between the cooling surface and the outer exposed surface.
