ABSTRACT:
The invention provides a liquid crystal display, including a transflective film having a PBS array with a satisfactory polarization property, to display a high-contrast image. A liquid crystal display includes an upper substrate and a lower substrate and facing each other, liquid crystal layers disposed between the upper substrate and the lower substrate, an upper polarizing layer disposed above the liquid crystal layers, and a lower reflective polarizing layer disposed below the liquid crystal layers. The lower reflective polarizing layer has a plurality of convex ridges having a triangle wave shape in cross-section and includes a multilayer dielectric film, disposed over the convex ridges, including a plurality of dielectric sub-layers; and the thickness of the multilayer dielectric film disposed on ridgeline portions of the convex ridges is less than or equal to 50% of the height of the convex ridges.
