Abstract: The present invention provides a liquid crystal medium composition and a liquid crystal display panel manufactured with same. The liquid crystal medium composition includes a negative type liquid crystal material, a polymerizable monomer, a sensitizer, and stabilizer. The sensitizer is an organometallic complex that has an amount of 0.01%-5% of total mass of the liquid crystal composition and has a strong absorption of ultraviolet light having a wavelength of 300-450 nm. The sensitizer converts the primary wavelength range of ultraviolet light for reaction of the polymerizable monomer from 200-300 nm to 300-450 nm, staying away from the absorption band of the liquid crystal material and reducing damages caused on the liquid crystal material and the alignment material of polyimide, thereby heightening reaction efficiency and homogeneity of the polymerizable monomer and the quality and lifespan of the liquid crystal display panel.

Abstract: An active-matrix liquid crystal display device having a pair of substrates at least one of which is transparent, a liquid crystal layer disposed between the pair of substrates, a group of electrodes for applying to the liquid crystal layer an electric field substantially parallel to the substrate plane and a plural number of active elements being formed on one of the pair of substrates and an alignment layer disposed between the liquid crystal layer and at least one of the pair of substrates. The alignment layer is a photo-reactive material layer, and the photo-reactive material layer is a photo-reactive alignment layer which has been subjected to linearly polarized light irradiation to selectively derive a photochemical reaction and a tilt angle of liquid crystal molecules on the alignment layer surface of the substrate is 3° or less.
