A7 1308658 ___B7___ V. DESCRIPTION OF THE INVENTION (丨) The present invention relates to the use of photoreactive dendrimers as alignment layers for liquid crystals and their construction in unstructured and structured optical elements and multilayer systems. Moreover, the invention also relates to novel photoreactive dendrimers. The success of a liquid crystal device depends on the ability of the liquid crystal molecules in the device to be used to maintain forced alignment. The alignment of the liquid crystal molecules is achieved by a directional layer that defines the orientation of the liquid crystal molecules in the device such that the longitudinal axis of the molecules becomes aligned with the orientation direction defined by the alignment layer. In addition to this directional alignment, the alignment layer can also impart a tilt angle to the liquid crystal molecules so that the molecules can self-align with the surface of the alignment layer at an angle rather than being tiled thereon. A tilt angle of from 1° to 15° is common for nematic liquid crystal displays (LCDs). However, some of the electro-optical effects for LCDs require an alignment layer with a very high forward tilt angle. For example, a vertically aligned nematic (VAN) LCD requires a forward tilt angle of between 85° and 90°, which is measured from the surface plane. In a hybrid aligned nematic (HAN) LCD, the front tilt angle at one of the substrates must fall within the above range, while the tilt angle at the other substrate is low (usually 0 to 10.). Methods of preparing alignment layers for liquid crystal materials are well known to those skilled in the art. However, conventional uniaxially polished polymer oriented layers, such as polyimides, suffer from a number of disadvantages such as dust generation during the rubbing process and breakage of the thin film transistor. In addition, the friction program does not produce a structured layer. The orientation layer in which the orientation direction can be illuminated by polarized light has long been known. This means that it is possible to avoid the problems inherent in the friction procedure. In addition to this, it is also possible to provide areas with different orientations, thus making the orientation 3 ------- . ___ This paper scale applies to the Chinese National Standard (CNS) A4 specification (210 >< 297 mm) -----------Install--------Book--------- (Please read the notes on the back and fill out this page) A7 1308658 ____B7____ V. Invention Description (7) Layer structure, as described in Upn. J. Appl. Phys., 31 (1992), 2155-2164 (Schadt et al.). In this method, a dimerization reaction of a polymer-bonded photosensitive cinnamic acid group induced by linearly polarized light irradiation is utilized, resulting in an anisotropic polymer network. These photo-aligned polymer networks can be used when a structured or unstructured liquid crystal alignment layer is desired. In addition to the use of the LCD, for example, the alignment layer can also be used to produce a so-called hybrid layer, as in US Patent No. 5,602,661, European Patent Application EP-A-0689084 (both F. Hoffmann-La Roche) AG) and those exemplified in WO-A-98/52077 (Rolic AG). Using these hybrid layers of photostructurable oriented polymer and polymerizable low molecular weight liquid crystal, it is possible to realize optical elements such as non-absorptive color filters, linear and circularly polarized germanium, optical retardation layers. For example, EP-A-0611786 and WO-A-96/10049 (both F_Hoffmann-La Roche AG) and EP-A-0763552 (Rolic AG) illustrate some of the principles that are suitable for the synthesis of such A cinnamic acid polymer of a photostructural alignment layer for a heterogeneously crosslinked liquid crystal. In the examples of the compounds described in EP-A-0763552 and WO-A-96/10049, when exposed to linearly polarized light, in addition to the desired orientation effect, it is also possible to simultaneously induce an inclination angle. This results in a layer having a structured surface orientation and a tilt angle. The photosensitive material for the alignment layer is also described in WO-A-99/49360 (Rolic AG), JP-A-10-195296, and JP-A-10-232400 (both of which are Samsung Electron Devices Co.). , Ltd.)), WO-A-99/15576 (R〇iic AG) and WO-A-99/51662 (4 This paper scale applies to China National Standard (CNS) A4 specification (210 x 297 public) (please Read the phonetic 3 on the back and fill out this page.)

Kanegafuchi Kagaku Kogyo KK). Illustrated in WO-A-99/15576 and WO-A-99/51662 are polyamidiamines incorporating a photosensitive cinnamic acid group in the side chain. Proposed in WO-A-99/49360, JP-A-10-195296 and JP-A-10-232400 are polymer blends comprising a photopolymer on one hand and a polyimine on the other. A disadvantage of these blends is their limited miscibility. However, low levels of photopolymers result in loss of directional properties, thus resulting in a decrease in the contrast of the liquid crystal layer to be oriented, while a reduced polyimine content results in a lack of retention ratio. Recently, a mixture of a liquid crystal monomer having a crosslinkable group and a photo-alignable monomer, oligomer or polymer is described in WO-99/64924. The layers of these mixtures can be photoaligned by linearly polarized light and subsequently or simultaneously crosslinked. Therefore, only a single layer is required to prepare a variety of different coatings, such as photo retarders, polarized light interference filters, structured polarizing prisms, and alignment layers for liquid crystals. The use of photo-alignable polymers in such mixtures results in good alignment. A disadvantage of these mixtures is that the miscibility between the polymer and the liquid crystal monomer is often limited, which has the risk of limited thermal stability, mainly due to phase separation of the annealing at elevated temperatures. On the other hand, it is known that low molecular weight photo-alignable materials which generally have good miscibility show poor alignment. In general, the resulting oriented layer will perform its function, in part, depending on the number of molecules in the layer that have been isomerized and/or dimerized by exposure to linearly polarized light. The degree of molecular isomerization and/or dimerization depends on the irradiation time, the irradiation energy, and the structure of the molecules to be irradiated. 5 I paper scale applies to China National Standard (CNS) A4 specification (210 X 297 public love ^ " ' ----------- loading -------- order ------ --- (Please read the notes on the back and fill out this page) A7 1308658 V. INSTRUCTIONS (&) However, the problem with low molecular weight materials used to prepare photo-aligned oriented layers is that there must be Cross-linking before irradiation and/or requiring a relatively long irradiation time to carry out isomerization and/or dimerization of the constituent molecules. In general, when a photo-alignable low molecular weight material is mixed with a liquid crystal monomer, The possibility of photoactive groups which can be isomerized and/or dimerized in the recorder is reduced. Therefore, a stable photoalignable material having short irradiation time, good miscibility and good processability is required. The present inventors have now discovered that photoreactive dendrimers can satisfy this need. Photoreactive dendrimers can be used to fabricate alignment layers for liquid crystals and structures for unstructured and structured optical components and multilayer systems. In one aspect, the present invention provides a novel photoreaction with good processability A dendrimer that, when exposed to polarized light for a relatively short period of time, results in a stable, high-resolution, mapable alignment layer that can also cause a tilt angle. These molecules have a low molecular weight material (such as liquid crystal monomer (LCP)) and Preferred miscibility between polymers. Further, crosslinkable or non-crosslinkable low molecular weight molecules having specific functional groups, such as acrylates, decanes, etc., can be readily incorporated into the mixture, or Chemically linked to the dendrimer' to control the properties of the object such as forward tilt, and to enhance adhesion and wettability and long-term mechanical, thermal and light stability.
