Liquid crystal display device

Abstract

The invention provides a liquid crystal display device. A liquid crystal panel of the device comprises a first substrate and a second substrate which are arranged oppositely up and down; and the first substrate and the second substrate respectively comprise one of a quantum dot color filter and an optical membrane. According to the liquid crystal display device, the quantum dot color filter and the optical membrane are arranged in different substrates, even the optical membrane has a relatively large refractive index, the interface total reflection is prevented from generating between the quantum dot color filter and the optical membrane, and a light emergence angle gathering outward a normal line due to refraction relationship is prevented, so that the interference of the refractive index of the optical membrane can be effectively eliminated and the display effect of the liquid crystal display device can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device. Background technique [0002] With the development of science and technology and the progress of society, people are increasingly dependent on information exchange and delivery. As the main carrier and material basis of information exchange and transmission, display devices have become a hotspot and highland that many scientists engaged in information optoelectronic research are vying to seize. [0003] Quantum Dots (Quantum Dots, referred to as QD) are invisible to the naked eye, extremely small inorganic nanocrystals, most of which are three-dimensional nanomaterials composed of II-VI or III-V elements. Due to the quantum confinement effect, the transport of electrons and holes inside it is restricted, so that the continuous energy band structure becomes a separated energy level structure. Whenever excited by external energy such as light or ...

Problems solved by technology

[0008] However, for figure 1 In the shown structure of the liquid crystal display device, when the refractive index of the optical film layer 22 is large, total reflection of the interface may occur between the quantum dot color filter layer 23 and the optical film layer 22, or the light may be scattered due to the relationship of refraction. The output angle gathers outside the normal line, which is not conducive to the display effect of the display device
