Definitions
- the present invention relates to novel polyorganosiloxanes, liquid crystal alignment films and liquid crystal display devices. More specifically, a polyorganosiloxane used for forming a liquid crystal alignment film, which is capable of providing a liquid crystal alignment ability by irradiation of polarized or non-polarized radiation without rubbing treatment, The present invention relates to a liquid crystal alignment film and a liquid crystal display device having such a liquid crystal alignment film.
- a nematic liquid crystal having positive dielectric anisotropy is formed into a sandwich structure on a substrate with a transparent electrode having a liquid crystal alignment film, and if necessary, the major axis force of liquid crystal molecules is continuously 0 to 360 degrees between plates.
- a liquid crystal table having liquid crystal cells such as TN (Twisted Nema tic) type, STN (Super Twisted Nema tic) type, IPS (I n PI n s s s s T i n c i s) type, etc., to be twisted. Indication elements are known (refer to JP-A-56-91277 and JP-A-1-120528).
- liquid crystal alignment film In such a liquid crystal cell, in order to align the liquid crystal in a predetermined direction with respect to the substrate surface, it is necessary to provide a liquid crystal alignment film on the substrate surface.
- the liquid crystal alignment film is usually formed by rubbing the surface of the organic film formed on the surface of the substrate with a cloth material such as rayon in one direction (labing method).
- a cloth material such as rayon in one direction (labing method).
- dust may be generated in the process, or static electricity may be generated, or dust may adhere to the surface of the alignment film to cause display defects.
- the problem was that.
- TFT Thin FilTransistor
- LCDs will be increasingly refined in the future In the display element, unevenness occurs on the surface of the substrate as the density of the pixels is increased, and therefore, it is a problem to uniformly perform the rubbing process.
- the photosensitive thin film made of polyvinyl cinnamate, polyimide, azobenzene derivative or the like formed on the substrate surface is irradiated with polarized or non-polarized radiation to impart liquid crystal alignment ability.
- Light distribution methods are known. According to this method, uniform liquid crystal alignment can be realized without generating static electricity and dust (Japanese Patent Application Laid-Open Nos. 6-287453, 10-251646, 11-2815).
- JP-A-11-152475 JP-A-2000-144136, JP-A-2000-319510, JP-A-2000-281724, JP-A-9-297313, JP-A 2003-307736 Gazettes, see JP-A 2004-163646 and JP-A 2002-250924).
- the liquid crystal alignment film aligns liquid crystal molecules at a predetermined angle with respect to the substrate surface. It is necessary to have pretilt angle characteristics.
- the pretilt angle is usually given by inclining the incident direction of the radiation to be irradiated onto the substrate surface from the substrate normal.
- a vertical (homeo mouth pick) alignment mode is also known in which liquid crystal molecules having negative dielectric anisotropy are vertically aligned to the substrate.
- this operation mode when a voltage is applied between the substrates to tilt the liquid crystal molecules in the direction parallel to the substrate, the liquid crystal molecules are tilted from the normal direction of the substrate toward one direction in the substrate surface.
- a method of providing a protrusion on the substrate surface a method of providing a stripe on a transparent electrode, and by using a rubbing alignment film, liquid crystal molecules are slightly directed from one direction normal to the substrate to one direction in the substrate surface. Methods such as pretilting are proposed.
- the photoalignment method is known to be useful as a method of controlling the tilt direction of liquid crystal molecules in a liquid crystal cell of vertical alignment mode. That is, alignment by photo alignment method It is known that the tilt direction of liquid crystal molecules at the time of voltage application can be uniformly controlled by using a vertical alignment film provided with a regulating force and a pretilt angle (Japanese Patent Laid-Open No. 2003-307736, Japanese Patent Laid-Open No. 2004-163646). JP, 2004-83, 810, JP, 9-211468, and JP, 2003-114437).
- the liquid crystal alignment film manufactured by the photoalignment method can be effectively applied to various liquid crystal display devices.
- the conventional photo alignment film has a problem that the radiation dose required to obtain a large pretilt angle is large.
- radiation with its optical axis tilted from the substrate normal must be irradiated at least 1 J / cm 2. (See, for example, JP-A-2002-250924, JP-A-2004-83810 and J. of S.ID 11/3, 2003 p. 579). Disclosure of the invention
