Liquid crystal display device and manufacturing method thereof

Abstract

The invention discloses a liquid crystal display device and a manufacturing method thereof. The liquid crystal display device comprises a first substrate and a second substrate opposite to the first substrate. A nematic liquid crystal layer is arranged between the first substrate and the second substrate. The nematic liquid crystal layer comprises nematic liquid crystals and a polymer network. According to the liquid crystal display device, the nematic liquid crystal layer is arranged between the first substrate and the second substrate and comprises the nematic liquid crystals and the polymer network, the polymer network is formed by illumination and polymerization of functional monomers in a nematic liquid crystal mixture, the polymer network can reduce the scattering phenomenon caused when refractive indexes of the liquid crystals and polymers are not matched, the dark state light leakage phenomenon is greatly reduced, and therefore the contrast ratio is improved; meanwhile, no polymer protrusions are arranged on an alignment layer, dark state light leakage caused by polymer protrusions is avoided, and therefore the contrast ratio is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device and a manufacturing method thereof. Background technique [0002] Currently, Liquid Crystal Display (LCD for short) is widely used in commercial products such as monitors, smart phones, and televisions due to its advantages of low power consumption, light weight, and thin thickness. However, liquid crystal display devices also have the disadvantages of limited viewing angle and slow liquid crystal response speed. In order to overcome the above-mentioned problems existing in liquid crystal display devices, liquid crystal display devices in the prior art usually adopt multi-domain vertical alignment technology or polymer stabilized alignment technology, which can realize liquid crystal display devices with wide viewing angles, and can improve the LCD response speed. [0003] Polymer protrusions are formed on the alignment layer of the liquid cryst...

Problems solved by technology

However, the scattering caused by the refractive index mismatch between liquid crystals and polymers can lead to dark-state light leakage; and because the alignment near the polymer protrusions is different from that in the areas where no polymer protrusions are placed, dark-state light leakage can also occur, thus leading to a decrease in contrast
