Abstract

The invention discloses a polarizing device and a preparation method thereof, a display panel and a display device. The polarizing device comprises a polarizing function layer; and an auxiliary functional layer which is arranged on the polarizing functional layer, wherein the auxiliary functional layer comprises a main body material and an additive, the thermal expansion coefficient of the additive is lower than that of the main body material, and the thermal conductivity of the additive is higher than that of the main body material. In this way, stress bending of the polarizing device in severe environments such as high temperature and high humidity can be improved and the quality reliability of products is improved.

Description

technical field [0001] The present invention relates to the technical field of polarizing devices, in particular to a polarizing device and a preparation method thereof, a display panel, and a display device. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements on the performance of display panels. Especially in harsh environments such as outdoors or high temperature and high humidity, people still hope that the display panel has stable display performance and a long service life. [0003] Polarizer, as an important component of liquid crystal display to achieve optical conversion, plays a vital role in the optical performance of the display. In the prior art, when the liquid crystal display is used outdoors, the outdoor temperature and humidity conditions are sometimes extremely harsh. Under high temperature and high humidity conditions, the polarizer will generate internal stress due to water absor...
