Abstract
The invention provides a liquid crystal display panel, a method for internally installing a polarizer in the liquid crystal display panel and a production method of the liquid crystal display panel. In the method for internally installing the polarizer in the liquid crystal display panel, the wire gating type internally installed polarizer is produced by adopting nanoimprint lithography, the problem that QDCF type products are difficult in on-off control can be solved when the produced internally installed polarizer is used on the liquid crystal display panel, the utilization rate of backlightis improved, the internally installed polarizer is set to be a sandwich structure, a first inorganic protective layer and a second inorganic protective layer are respectively arranged on two sides ofthe metal wire gating layer, the metal wire gating layer can be prevented from oxide etch, and service life of the internally installed polarizer is prolonged.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a method for building a polarizer in a liquid crystal panel, a liquid crystal display device and a manufacturing method thereof. Background technique [0002] Thin Film Transistor-LCD (Thin Film Transistor-LCD, TFT-LCD) has been developed rapidly and widely used in recent years. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. Usually, a liquid crystal display panel consists of a color filter (ColorFilter, CF) substrate, a thin film transistor (Thin Film Transistor, TFT) substrate, a liquid crystal (Liquid Crystal, LC) sandwiched between the color filter substrate and the thin film transistor substrate, and a sealant (Sealant) ) composition; its working principle is to control the rotation of the liquid crystal molecules in the liquid crystal laye...
