Abstract
A polarizer and a display device are provided. In the polarizer, on a basis of using an optical compensation layer to compensate a birefringence of liquid crystal molecules in a liquid crystal layer, a liquid crystal compensation layer is configured to compensate the birefringence of the liquid crystal molecules in the liquid crystal layer. The liquid crystal compensation layer adjusts a compensation value through a refractive index difference and a thickness of the liquid crystal molecules, so an adjustment range is large and a restriction is small, which can be matched with a high phase difference of the display device, and further improves side-view light leakage in a dark state of the liquid crystal display.
