HIGHLY BRIGHT POLARIZATION SHEET CAPABLE OF SECURING SCRATCH RESISTANCE WHICH OBTAINS HIGH POLARIZATION AND HIGH BRIGHTNESS BY A BIREFRINGENT MICROFIBER AND THE BACK LIGHT ASSEMBLY OF A LIQUID CRYSTAL DISPLAY DEVICE INCLUDING THE SAME

摘要

PURPOSE: A highly bright polarization sheet and the back light assembly of a liquid crystal display device including the same are provided to form high polarized light and high brightness using a birefringent microfiber.;CONSTITUTION: A polarization sheet enhances condensing efficiency by the prism effect of a pyramid pattern when incident light is reaches a pattern layer(20). The incident light passes through the reflective fiber polarization film layer consisting of the birefringence microfiber(11). The upper part of the pattern layer is round and scratch resistant and is secured when contacting or assembling with a panel.;COPYRIGHT KIPO 2012
