Abstract
The present invention discloses a polarizing device, a preparation method thereof, a display panel, and a display device. The polarizing device includes: a polarizing functional layer; and an auxiliary functional layer disposed on the polarizing functional layer, wherein the auxiliary functional layer includes a host material and an additive, a thermal expansion coefficient of the additive is less than that of the host material, and a thermal conductivity of the additive is greater than that of the host material. In the above way, the present invention can improve stress bending of the polarizing device in a severe environment such as high temperature and high humidity, and improve quality and reliability of product.
