Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a liquid crystal composition and a display panel. Background Art

[0002] Liquid crystal materials are widely used in various display devices such as mobile phones, televisions and computers. Liquid crystal plays the role of a "light valve" in a thin film transistor liquid crystal display (TFT-LCD), which controls the amount of backlight transmitted to adjust the brightness of the display device.

[0003] The traditional vertical alignment (VA) liquid crystal display panel consists of a TFT substrate, a color filter (CF) substrate, a polyimide (PI) alignment layer and a liquid crystal composition sandwiched between the two substrates. The liquid crystal molecules in the liquid crystal composition are vertically aligned through the PI alignment layer. When the external voltage is 0V, the long axis direction of the liquid crystal molecules in the VA mode display is perpendicular to the glass substrate; after the natural light passes through the polarizer on the TFT substrate side, it forms linearly polarized light. At this time, its polarization state and polarization direction cannot be changed by the liquid crystal molecules, and thus it is absorbed by the polarizer on the CF substrate side, that is, the incident light perpendicular to the glass substrate cannot pass through, and the display presents a dark state effect. Therefore, VA mode display devices usually have negative dielectric anisotropy (Δε) and high contrast.

[0004] However, the transmittance of liquid crystal display panels still needs to be improved. Summary of the invention
