Abstract
A polarizer and a manufacturing method thereof, a display panel, and a display device are provided. The polarizer includes a polarizing layer, and the polarizing layer includes a first polarizing region and a second polarizing region. A light transmittance of the first polarizing region is greater than a light transmittance of the second polarizing region, and a ratio of the light transmittance of the first polarizing region to the light transmittance of the second polarizing region is 1.1:1 to 2.6:1.
