Polarizer and manufacturing method thereof, display panel and display device

Abstract

The invention describes a polarizer and a manufacturing method thereof, a display panel comprising the polarizer and a display device. According to the embodiment of the invention, the polarizer provided by the invention comprises a first transparent layer, a second transparent layer arranged opposite to the first transparent layer, a polarizing layer arranged between the first transparent layer and the second transparent layer, and a first organic layer arranged between the first transparent layer and the polarizing layer, or a second organic layer arranged between the second transparent layer and the polarizing layer, wherein the shrinkage stress direction of the first organic layer or the second organic layer is vertical to that of the polarizing layer. The polarizer provided by the embodiment of the invention comprises the polarizing layer and the organic layer, wherein the shrinkage stress direction of the organic layer is vertical to that of the polarizing layer; when the outer surface of the display panel is attached with two polarizers, the shrinkage stresses of the upper polarizer and the lower polarizer are balanced, so that the display panel is less likely to warp.

Description

technical field [0001] The invention relates to the field of optics, in particular to a polarizer, a manufacturing method thereof, a display panel and a display device including the polarizer. Background technique [0002] In recent years, due to the thinning and thinning of display screens and the increase in contrast, the polarizers required for them also need to have higher quality. Regardless of whether it is a small-size or a large-size display screen, a polarizer with a thinner thickness is required to meet its light and thin requirements. [0003] One of the key components of liquid crystal displays is the polarizer, figure 1 is the structural diagram of the polarizer in the prior art, such as figure 1 As shown, the polarizer includes a release film 1, an adhesive layer 2, a first light-transmitting film 3, a polarizing film 4, a second light-transmitting film 5, and a protective film 6 that are sequentially stacked. The first light-transmitting film 3 The material...

Problems solved by technology

However, this measurement method is not feasible due to the difference in the sampling position and the accuracy of the instrument error range.

[0006] In addition, it is known that the TAC film with different warping directions is bonded to the polarizing layer, or the thickness of the film and the distance between the roller and the bonding wheel before bonding are proportional to a ratio and the ratio is controlled to be less than 60, thereby Suppresses the warping of the manufactured polarizer. However, this method cannot obtain better reproducibility on different brands of machines due to the different operating mechanisms of the machines.
