The liquid crystal display device contains substrates arranged as opposed to each other through a liquid crystal; a pixel electrode and a counter electrode for generating an electric field between the pixel electrode and the counter electrode, provided on a pixel region on a surface on a side of the liquid crystal of one of the substrates; and a charge transporting layer provided to cover the pixel electrode and the counter electrode, in which the pixel electrode and the counter electrode are formed in the same layer on one plane, and the liquid crystal has a resistivity of less than 1×1013 ?·cm.

Abstract: It is Possible to enhance the utilization efficiency of a light source and impart an orientation control performance and a pretilt angle to an orientation film in a short treatment time. Substrates to which orientation films are applied are mounted on stages which are sequentially transported to a main irradiation region and a sub-irradiation region. Light flux irradiated from a light source device having a single light source receives polarization treatment at a polarization unit, thus generating main polarized light and a sub-polarized light. The main polarized light is irradiated to the orientation film formed on the substrate which is transported to a main irradiation region, thus imparting orientation control performance to the orientation film. Subsequently, the substrate is transported to a sub-irradiation regions and sub-polarized light is irradiated to the orientation film to which orientation control performance is already imparted, thus imparting a pretilt angle to the orientation film.

Abstract: A liquid crystal display device can obviate the generation of an extinction pattern. In the liquid crystal display device, molecules of liquid crystal interposed between respective substrates which are arranged to face each other in an opposed manner are arranged in the vertical direction with respect to the substrate at the time of applying no voltage.

Abstract: A liquid crystal display device which is constructed to restrain the occurrence of ionic image retention includes substrates disposed in opposition to each other with a liquid crystal being interposed therebetween, a pixel electrode formed in each pixel area on a liquid-crystal-side surface of one of the substrates, a counter electrode which generates an electric field between itself and the pixel electrode, and alignment films disposed in contact with the liquid crystal on the liquid-crystal-side surfaces of the respective substrates. The liquid crystal has a positive or negative dielectric anisotropy, and each of the alignment films is made of a material containing a diamine structure which traps ionic impurities.

Abstract: There are provided a liquid crystal display device and a manufacturing method therefor both of which is arranged to eliminate display irregularity in the vicinity of the liquid crystal injecting port of a liquid crystal panel and provide good display in the entire display area. In the liquid crystal panel, a lower substrate having thin film transistors for switching for pixel selection on its inside surface and an upper substrate having color filters for plural colors on its inside surface are disposed in opposition to each other with a layer of a liquid crystal compound being interposed therebetween, and the lower substrate and the upper substrate are stuck to each other by a sealing material which is arranged to surround a display area of the upper substrate and has, in a portion, a cut which serves as a liquid crystal injecting port.

Abstract: Creation of display image burn-in phenomena otherwise occurring due to the presence of an internal residual voltage(s) is suppressed. The polarization relaxation time constant &tgr; of a dielectric film layer existing between a liquid crystal drive electrode and a liquid crystal layer is specifically set to fall within a range of five minutes.

Abstract: In a liquid crystal display panel, the shrinkage of an end-scaling material for sticking a pair of substrates together is prevented or relaxed to restrain peeling of the end-sealing material from the substrates, thereby preventing any leakage of a liquid crystal and penetration of contaminants. A liquid crystal display device is assembled by bonding together a pair of substrates, which are opposed to each other across a predetermined gap and at least one of which has an electrode group formed over a surface opposed to the other substrate, with a sealing material along their peripheries excluding a liquid crystal filling port, and then sealing the liquid crystal filling port with an end-sealing material after the filling of the liquid crystal and hermetically sealing the liquid crystal in the gap between both substrates. In the liquid crystal display device, a resin which constitutes the end-sealing material contains particulates of average particle size of 0.1 &mgr;m to 3.
