Liquid crystal display panel and liquid crystal display device

Abstract

The invention discloses a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises a polarizer, a first substrate, a liquid crystal layer, a secondsubstrate, and a quantum dot polarizer; the polarizer comprises a first protective layer and a first polarizing layer; the quantum dot polarizer includes a second protective layer and a second polarizing layer; the absolute value of the difference between the thickness of the first protective layer and the thickness of the second protective layer is within a preset threshold. In the above manner,the present invention can reduce the difference in thickness between the polarizer and the quantum dot polarizer, thereby making the liquid crystal panel less prone to warpage.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] In recent years, novel display technologies such as organic light-emitting diode electroluminescence, laser display, and Micro LED have developed rapidly. Against this background, liquid crystal displays are also constantly being updated, using new technologies to make up for their own shortcomings. Due to the excellent performance of quantum dot materials such as high color purity and continuously adjustable spectrum, quantum dot materials have become the most widely studied luminescent materials in the 21st century. [0003] In the long-term research and development process, the inventors of the present invention found that in the prior art, when the glass substrate is not subjected to external force, the glass substrate itself is not prone to warping. The usual str...

Problems solved by technology

The PVA layer in the polarizer is formed by stretching the polymer chain material. The PVA layer is not water-resistant, and the PVA layer is easily caused to shrink the molecular chain after being heated and damp, resulting in a certain degree of tension between the first polarizer and the second polarizer. stress, therefore, can cause the LCD panel to warp

And the greater the difference between the thickness of the first polarizer and the thickness of the second polarizer, the greater the difference in stress, which makes the liquid crystal panel more likely to warp
