    • PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of efficiently inducing a splay-bend transition.
      SOLUTION: A plurality of minute structural bodies 31 are formed on a TFT substrate 3. The minute structural body 31 includes a side (a) along a rubbing direction X in which rubbing treatment is performed first and a side (b) along a rubbing direction Y in which rubbing treatment is performed second and an angle θ1 formed by the rubbing directions X and Y is specified to be an angle (a vertex angle) θ2 formed between the sides (a) and (b). Two minute regions having twisted structures having twisted arrangements of liquid crystal molecules different from each other when voltage is applied can be formed by performing rubbing treatment using the minute structural bodies 31. The splay-bend transition can be induced by forming the two minute regions.

    • 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
