Abstract: Some embodiments of the present application disclose a polarizer and a display device, wherein the polarizer includes a polarizing layer, and a first optical functional layer on a side of the polarizing layer. The first optical functional layer includes a substrate and light-diffusing particles dispersed in the substrate. An average value of a difference between an orientation angle of an orthographic projection of a long axis of the light-diffusing particle in a first plane and an orientation angle of an absorption axis of the polarizing layer in the first plane is less than or equal to 5°.
