An optical property, particularly improved off-axis lightness, over a wide viewing angle range and having a broad band encompassing a substantial portion of the visible spectrum of light, ideally visible. Provided is a broadband reflective polarizing plate having a band covering the entire spectrum. It has a layer of a polymerized mesogenic material exhibiting a helical twisted molecular structure with Rena orientation, and a) at least one non-chiral polymerizable mesogenic compound, b) polymerizable and / or intermediate phase formation A mixture of chiral polymerizable mesogenic materials containing at least one chiral compound, c) a polymerization initiator, which can also be functional, applied in layers on a substrate or between two substrates, and A broadband reflective polarizer obtained by the method, oriented in a planar orientation such that the axis extends transverse to this layer and then polymerized by exposure to heat or actinic radiation.
