    摘要： Decreasing the non-uniformity of display by photo-deterioration of the liquid crystal material is achieved in order to provide high grade liquid crystal display devices. A pair of substrates holding a liquid crystal layer between them are adhered together with a resin, and at least an opening for injecting liquid crystal into the interval between the pair of substrates is provided in the resin portion. The opening is sealed with a photo-curable resin. The liquid crystal layer contains a photo-reactive liquid crystal compound, the molecular structure of which is converted by a photo-irradiation, and an photo-absorbing organic compound having a photo-absorptivity larger than that of the photo-reactive liquid crystal compound at a designated wavelength, and containing at least one of alkyl substituent, alkenyl substituent, and alkoxyl substituent of 1-8 carbon atoms, respectively, in its molecule.

    摘要： A liquid crystal display device can suppress the local temperature elevation of a liquid crystal in the vicinity of drivers. On a liquid-crystal-side surface of one substrate out of substrates which are arranged to face each other in an opposed manner while sandwiching a liquid crystal therebetween, a switching element which is operated in response to scanning signals from a gate signal line, a pixel electrode to which video signals from a drain signal line are supplied via the switching element, and a reference electrode which generates an electric field between the reference electrode and the pixel electrode are mounted on each pixel region of the liquid-crystal-side surface. The video signals from the drain signal line are generated by a driver chip mounted on one substrate. A light transmittivity of the liquid crystal layer is set to take a minimum value when a voltage is not applied between the pixel electrode and the reference electrode. A maximum amplitude of voltage of the video signals is set to a value not more than a voltage necessary for setting a relative transmittivity of the liquid crystal layer to 90%.
