Abstract: In a liquid crystal display device, a common electrode is formed on an organic passivation film, an interlayer insulating film is formed on the common electrode, a pixel electrode with a slit is formed on the interlayer insulating film, and a through hole is formed in the organic passivation film and the interlayer insulating film, so that the pixel electrode is connected to a source electrode of a TFT through the through hole. Further, the taper angle around the upper base of the through hole is smaller than the taper angle around the lower base. Thus, the alignment film material can easily flow into the through hole when the diameter of the through hole is reduced to connect the pixel and source electrodes, preventing display defects such as uneven brightness due to the absence of the alignment film or due to the alignment film irregularity around the through hole.

Abstract: The present invention provides a method for manufacturing a liquid crystal display device which requires a reduced light irradiation dose in the alignment treatment for a photo-alignment film and achieves a favorable contrast ratio and a viewing angle property. The method for manufacturing a liquid crystal display device includes, in the following order, the steps of: (1) forming on a substrate a film of a photo-alignment film material containing two or more polymers and a solvent; (2) pre-baking the film to evaporate the solvent; (3) post-baking the pre-baked film gradually at multiple temperatures from a low temperature to a high temperature; and (4) irradiating the post-baked film with polarized light, at least one of the two or more polymers being a photo-reactive polymer containing a photo-functional group in a side chain.

Abstract: The present invention relates to liquid-crystalline media (LC media) having negative or positive dielectric anisotropy, comprising a low-molecular-weight component and a polymerizable component. The polymerizable component comprises self-aligning, polymerizable mesogens (polymerizable self-alignment additives) which effect homeotropic (vertical) alignment of the LC media at a surface or the cell walls of a liquid-crystal display (LC display). The invention therefore also encompasses LC displays having homeotropic alignment of the LC medium without alignment layers. The invention discloses novel structures for self-alignment additives which have a certain position of the functional groups.
