Description

201113332 VI. Description of the Invention: [Technical Field to Be Invented by the Invention] The present invention relates to a novel dichroic dye and a light absorbing heterogeneous f-film. Further, the present invention relates to a polarizer and a display device using the light absorbing anisotropic film. Further, the present invention is also directed to a method of manufacturing the electron. [Prior Art] - ^ It is necessary to include the attenuation function of the illumination light of the laser light or the natural light, the polarization function, the brain function, the shading function material, and previously, the device which is divided into different functions by the different principles is used to exert the Wei. Therefore, with these functions, the corresponding products are also manufactured by the (four)_manufacturing steps for each function. The team will control the two day and day; _ and jin shot! · Straight using polarized plates or circular polarized lights. In the light-emitting element, a circular polarizing plate is also used to prevent the polarizing plate (polarized photo) of the external light from being widely used as a two-color, and the second is sufficient for the partial 2f because of the sublimation property. Its extinction color is dark blue, and it can't be called: ideal eclipse photon in the visible spectrum region. Therefore, it is being studied in _ money (4) & sub-color == quality = A polarizing ratio of a degree of dichromaticity is obtained, and the optical rotation or birefringence of light is used for the recognition, and it is an important constituent element. In recent years, the bias has been shown to improve the display performance and the like. - 4 201113332 In the development of new polarizers. Earth's method: an organic pigment similar to a hard photon (two-color ^ = thin, -) or the like: the film extends in one direction In the case of a process such as a glass film or a transparent film, the film is used for the process of stretching, etc., but it has recently been focused on other methods. The molecules of the _ _ mutual material to make the dichroic pigment alignment, shape = pigment film) ° but I have In the method described in the literature (4), the thermal alignment of the substrate is performed on a substrate such as a glass or a transparent film by using an organic color interaction or the like, and the tetrachromatic pigment is aligned by a wet film formation. When a heterogeneous pigment film is produced by a membrane method, a dye suitable for the wet film formation method other than the high dichroism of the dye molecule is required for the dye used in the dye film. The process includes a method of depositing and aligning a pigment on a substrate, a method of controlling the alignment thereof, and the like. Therefore, many pigments which can be used for the polarizer which has undergone the above-described extension treatment are often not suitable for the wet film formation method. Patent Documents 1 to 3 propose materials suitable for the above process. However, although these materials are suitable for the process, they have a problem that they cannot exhibit high dichroism. ^ In addition, regarding the process suitable for the process In the material, Patent Document 4 proposes a dye represented by (chromogen) (S〇3M) n*. 201113332 Patent Document 5, which is aligned from the gas phase on the alignment film. In the sixth, the pigment molecules are exposed and the liquid crystal azo dye is spin-coated and aligned to the alignment film, and a sulfonic acid group is coated on the photoactive molecule. , amine or hydroxyl group, etc.: generation = film [aligned photon]. Patent 2 fTF is applied to the photo-alignment film to coat the composition of black dichroism in ultraviolet curable liquid crystal (so-called f ^ The yoke formed by the alignment. However, it is quite inferior to the dichroism, and it is impossible to develop the use of the partial element in order to improve the display performance. It is proposed in Document 1 that a polarizing layer (so-called intracellular first layer) is provided between the sheet layer and the liquid crystal material layer to suppress depolarization of the color light guide sheet. However, the liquid crystal layer disposed on the liquid layer must have a thinner film thickness to achieve the desired degree of polarization and a more dichroic property.
