Title:
REFLECTIVE POLARIZING MODULE HAVING DIFFUSION PATTERN AND BACKLIGHT UNIT INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2016/195300
Kind Code:
A1
Abstract:
The present invention provides a reflective polarizing module that comprises: a reflective polarizing sheet having a plurality of layers with different refractive indices stacked one above another to selectively transmit light; a first light-condensing sheet having a first structuralized pattern in which first unit light-condensing bodies are continuously repeated, wherein each of the first unit light-condensing bodies has a gradually decreasing transverse cross-sectional area from the lower portion to the upper portion of the reflective polarizing sheet, and the upper end of the first unit light-condensing body is bonded to the lower portion of the reflective polarizing sheet so as to have a first width in the transverse direction; and a coating layer located on the upper surface of the reflective polarizing sheet and having a diffusion pattern formed on the upper surface thereof to diffuse light transmitted through the reflective polarizing sheet, the diffusion pattern being constituted by a plurality of diffusion protrusions protruding from the upper surface of the coating layer, wherein at least some of the plurality of diffusion protrusions are formed to have a transverse width relatively smaller than the first width.
