Abstract:
1. A Liquid Crystal Display (LCD) device comprising: a panel on which images are implemented; a backlight device below the panel and providing light; and a polarizer comprising a linear-polarizing layer over the panel that linear-polarizes light from the backlight device and a circular-polarizing layer over the linear-polarizing layer that circular-polarizes the linear-polarized light, wherein the polarizer is configured in sequence of an adhesion layer (PSA) adhered to the panel, a lower Tri-Acetyl-Cellulose (TAC) on the adhesion layer, a Poly-Vinyl-Alcohol (PVA) layer on the lower TAC, a Quarter Wave Plate (QWP) on the PVA layer and an upper TAC on the Quarter Wave Plate (QWP), wherein the upper TAC protects the Quarter Wave Plate (QWP) from an external force, and the upper TAC is applied by the interface treatment such as the hard coating or the low reflective treatment, to decrease the reflexibility reflected through the polarizer in the high illuminance environment so that the contrast ratio is increased, the light fadedness phenomenon is improved and the outdoor visibility is enhanced.
