摘要： A liquid crystal display device of the invention can, when a liquid crystal panel receives a pressing force from the outside, prevent the displacement of columnar spacers which are formed over a counter substrate for defining a distance between the counter substrate and a TFT substrate in the direction parallel to the substrate. In a case where the TFT substrate or the counter substrate receives a pressing force from the outside, when the columnar spacers which define the distance between the TFT substrate and the counter substrate are displaced in one or more directions, the alignment disorder of liquid crystal molecules occurs or an alignment film is shaved so that leaking of light occurs due to shaved chips of the alignment film and hence, contrast of an image is lowered. Projections are formed on a TFT substrate side by making use of bus electrodes provided for preventing lowering of a voltage of counter electrodes. When the TFT substrate or the counter substrate receives a pressing force from the outside, the projections bite into a distal end of the columnar spacer so that the displacement of the columnar spacer in one or more directions can be prevented.

摘要： An image retention phenomenon and black unevenness generated after long-time operation in the liquid crystal device are prevented. By using a material having a polyamide acid ester as a precursor less likely to adsorb impurities on a boundary for an alignment film and a material having a dielectric constant anisotropy Δ∈ of 5 or less for liquid crystals, adsorption of an antioxidant dispersed in the liquid crystals is suppressed to prevent oxidation of the liquid crystals. The extent that impurities are intruded into the liquid crystals is reduced by restricting the dielectric constant anisotropy Δ∈ of the liquid crystals to 5 or less, thereby capable of preventing the image retention phenomenon and the black unevenness.

摘要： The present invention is directed to a VA-mode liquid crystal display panel wherein, by radiating light such as ultraviolet rays to a first alignment film, main chains in molecules of the alignment film are arranged to form a first slow axis. By also radiating the light to a second alignment film, a second slow axis is formed. The first slow axis and the second slow axis are arranged to cross each other. When an electric field is applied to a liquid crystal layer, liquid crystal molecules tilt in the direction which crosses the extending direction of projections formed on a substrate. The projections are formed such that the direction along which the liquid crystal molecules tilt and a first slow axis or a second slow axis differ from each other.

摘要： The present invention compensates for a viewing angle of a VA-mode liquid crystal display device without using an expensive viewing angle enlarging film. In a VA-mode liquid crystal display panel, by radiating light such as ultraviolet rays to a first alignment film, main chains in molecules of the alignment film are arranged to form a first slow axis. By also radiating the light to a second alignment film, a second slow axis is formed. The first slow axis and the second slow axis are arranged to cross each other. When an electric field is applied to a liquid crystal layer, liquid crystal molecules tilt in the direction which crosses the extending direction of projections formed on a substrate. The projections are formed such that the direction along which the liquid crystal molecules tilt and a first slow axis or a second slow axis differ from each other.
