摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of quickly and stably aligning liquid crystal molecules in a liquid crystal layer, from a spray state to a bend state even without having to apply a high voltage, and to provide a manufacturing method of the liquid crystal display device. SOLUTION: An alignment film of the liquid crystal display device includes a first region which is uniformly subjected to a first alignment in a first direction; and a second region which is subjected to a second alignment in a second direction substantially orthogonal to the first direction and in a third direction that is reverse to the first direction, with respect to fine regions in the alignment film after the first alignment. In this case, the first region may be an optically aligned region, or the second region may be an optically aligned region. When optical alignment is to be carried out, the region to be given optical alignment is, for example, selectively irradiated with ultraviolet rays. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device which enables alignment of liquid crystal molecules in a liquid crystal layer to be quickly and stably shifted from a splay state to a bend state without application of a high voltage and which can stably generate such shifting as above.
SOLUTION: The entire surface of an alignment film on the substrate surface of a substrate 3 is subjected to first alignment treatment (treatment for overall surface uniformity) such as rubbing in a direction (a). Next, regions narrower than the region subjected to the first alignment processing in the direction (a) are subjected to second alignment processing in a second direction (b) forming about 90° to the direction (a) and a third direction (c) opposite to the direction (a). As a result, minute regions 31 subjected to alignment processing in directions (a) to (c) are present in intersections between directions (b) and (c). Respective minute regions 31 are formed within light shielding parts.
