Provided is a light concentrating module capable of reducing bending, comprising: a reflective polarization sheet layered with a plurality of stacks having different refractive indexes, so as to selectively transmit light, and having both sides of which the contraction rates are different; and a first light concentrating sheet having a first structurization pattern in which first unit light concentrating bodies, of which cross-sectional areas gradually decrease towards an upper part thereof, are successively repeated, wherein the first unit light concentrating bodies are attached to one surface of the reflective polarization sheet, thereby reducing the contracting and bending of the reflective polarization sheet according to a rise in the temperature, caused by a difference between the contraction rate of the first light concentrating sheet and the contraction rate of one surface of the reflective polarization sheet. |
