Description of the Invention: [Technical Field] The present invention relates to a liquid crystal alignment structure of a liquid crystal display. [Prior Art] Liquid crystal display 7FII is a basic element of the crystal molecular material. The self-made liquid crystal molecules can be combined into a currently popular and often life-related liquid crystal display device between the W glass plates which are subjected to the alignment treatment. Between the dielectric state and the liquid state of the liquid crystal molecule, not only does the liquid (4) flow under the action of an external force, but also has the unique directional property of the crystal, so that an external force: an electric field can be used to drive the alignment state of the liquid crystal to other orientations. The optical properties of the light passing through the liquid crystal layer are changed. This is the applied electric field to produce the modulation phenomenon of light, which is called the light of m. _Discrimination produces a variety of touch crystal display crying, such as twisting TN-TwistedN reward) LCD display, super twisted nematic (sw-SuperTO) liquid crystal display, and _f day and day body (τρτ-τΐιίηΐ^ Τ_ Liquid crystal display, etc. Take the action principle of the twisted nematic liquid crystal display as an example, please refer to the figure __ a, b, Figure 1A, B are the schematic diagrams of the action of the twisted nematic liquid crystal display. Please refer to Figure 1 first. A. The twisted nematic liquid crystal display device 100 mainly includes polarizing plates 13A and 14B which can form a fine groove 105 and a crystal alignment film (10) and (10) by polishing (four) to polarize the direction of the scattered light source. When the nematic crystal 15 (four) is injected between the liquid crystal alignment films ιι, 120, the nematic liquid crystal i (d) molecules have liquid flow characteristics, and therefore are easily aligned in the direction of the grooves 105, 106. At the 1〇6 position, the nematic liquid crystal 150 is subjected to a large binding force, so that it is arranged along the groove (10) and the contact direction, and the intermediate portion of the nematic liquid crystal (9) has a small binding force and is twisted. As of 1271589 (Case No. 093128120) Correction of the specification) Since the nematic liquid crystal 150 in the liquid crystal alignment films 110 and 120 is twisted by a total of 9 degrees, it is called a twisted nematic type. Therefore, when no voltage is applied between the liquid crystal alignment films 110 and 120, the light is After the polarizing plate 140 and the liquid crystal alignment film 12 are inserted, the direction thereof is rotated by 90 degrees with the arrangement of the liquid helium 15〇 and the polarization direction of the polarizing plate 130 is the same, and the light can smoothly penetrate the polarizing plate 130. Please refer to In FIG. 1B, when a voltage is applied between the liquid crystal alignment films 11 and 12, the nematic liquid crystal 150 will tend to be parallel to the direction of the applied electric field, and thus the nematic liquid crystal ι5 〇__ is perpendicular to the liquid crystal alignment films 110 and 120. After reaching the polarizing plate 13〇, the light cannot penetrate the polarizing plate 130. Therefore, by controlling the voltage between the liquid crystal alignment films 110 and 120, a bright-dark contrast display effect can be obtained, which is a twisted nematic liquid crystal display. 100 shows the principle of operation of the black-and-white screen on a white background. However, due to the arrangement of the alignment directions of the grooves 105 and 1〇6 on the liquid crystal alignment films 110 and 120, the viewing angle characteristics of the twisted nematic liquid crystal display 1 受到 are limited, The face view of the panel without the two-compensation in the viewing angle will be contracted in the horizontal and vertical directions. It has left-right symmetrical but up-and-down asymmetrical viewing angle characteristics before uncompensated, and its corresponding liquid crystal alignment film configuration Please refer to Figure 2, which is a schematic diagram of the alignment direction of the conventional liquid crystal alignment film. Generally, when the liquid crystal alignment films 210 and 220 are in the alignment process, the alignment angles of the upper and lower glass are 45 degrees in the horizontal or vertical direction or Grinding and aligning is carried out in a manner of 135 degrees. Referring to FIG. 3, FIG. 3 is a schematic diagram showing the viewing angle characteristics of the liquid crystal alignment film after the 45-degree or 135-degree alignment direction is used for the twisted nematic liquid crystal display. It can be seen from Fig. 3 that the liquid crystal alignment film of the 45-degree or 135-degree alignment direction will cause the twisted nematic liquid crystal display to exhibit a kneading surface, and the viewing angle characteristic is retracted in the direction of extension of 90 degrees and 18 degrees, especially in the direction of 90 degrees. The upper contraction situation is the most serious. For the user who is watching the liquid crystal display, the viewing angle of the liquid crystal display in the direction of 9 degrees and 180 degrees is more important, so the well-known liquid 1271589 (Case No. 093) 2812〇 Correction of the specification of the patent application) The orientation of the crystal alignment on the film is not appropriate. In view of the above, the present invention provides the remaining structure to the structure of the liquid crystal alignment structure so that the viewing angle characteristic displayed on the liquid crystal display screen can be expanded in the extending direction of ninety degrees and one hundred and eighty degrees. SUMMARY OF THE INVENTION The main object of the present invention is to enable a twisted nematic liquid crystal display to expand in a display direction of ninety degrees and one hundred and eighty degrees. In order to achieve the object, the present invention proposes a liquid crystal alignment structure, a liquid crystal alignment structure, which is turned over to use - twisted nematic = crystal molecules: a display comprising a first liquid crystal alignment film and a second liquid crystal alignment film . Wherein the 'first-liquid crystal alignment lining is disposed on the surface of the first glass facing the twisted nematic liquid crystal molecules in an orientation direction of ninety degrees. The second liquid crystal alignment is disposed on the surface of the second glass-twisted nematic liquid crystal molecule in an alignment direction of one hundred and eighty degrees. In a preferred embodiment of the invention, the liquid crystal alignment structure further includes a first polarizing plate and a second polarizing plate 1. The first polarizing plate is disposed in a direction of the first glass relative to the first liquid crystal alignment film. The second polarizing plate is disposed in the second direction relative to the direction of the second liquid crystal alignment film. [Embodiment] In order to enable the reviewing committee to have a further understanding and understanding of the features, purposes and functions of the present invention, the detailed description of the following figure is as follows: A schematic diagram of a liquid crystal alignment structure of a twisted nematic liquid crystal display. When the liquid crystal alignment film and the sample are aligned, the polishing alignment is performed at a direction of an angle of 90 degrees. In this case, it can be found that the picture presented by the twisted nematic liquid crystal display can be expanded in the direction of extension of 90 degrees and 180 degrees. 1271589 (correction of the specification of the patent No. 093128120) Therefore, by the liquid crystal alignment structure of the present invention, the screen of the liquid crystal display screen (4) can be expanded in the direction of extension of 90 degrees and 180 degrees, in order to comply with the liquid crystal display. The requirements displayed on the screen. According to the concept of the present invention, the present invention further proposes a liquid crystal alignment structure, which is matched with a polarizing plate by a liquid crystal alignment film. It is expected that the direction of the polarizing plate is also changed according to the alignment direction of the liquid crystal alignment film of the liquid crystal alignment structure. The picture displayed by the liquid crystal display screen is more optimized. Referring to Figure 5, Figure 5 is a schematic representation of the apparent purity of the displayed image of a twisted nematic liquid crystal display device in accordance with a preferred embodiment of the present invention. In the five-necked, the screen displayed by the steering liquid crystal display has a significant expansion in the direction of extension of 90 degrees and 180 degrees, and the display area of the display screen is very large. - month reference figure /, Fig. 6 is a schematic view of a liquid crystal alignment structure of a preferred embodiment of the present invention. In FIG. 6, the liquid crystal alignment structure 5 is a liquid crystal alignment film 501, 503 which is used in a direction of 9 以及 and 18 〇, and the liquid crystal alignment film 5 (H, 503 is respectively disposed on the surface of the glass 5, 5, 507). The liquid crystal alignment structure 500 further includes polarizing plates 513 and 515 which are respectively disposed in the direction of the glass 505 and 507 with respect to the liquid crystal alignment films 501 and 503. The polarizing plate 513 facing the light source is composed of a compensation film 530, a transparent substrate 58, a polarizing sub-layer 540, a transparent substrate 583, and a brightness enhancing film 570. The polarizing plate 515 facing the viewer is composed of a compensation film 520 and a transparent substrate. 587, a polarizing sub-layer 550, a transparent substrate 585, and an additional functional film 560. It is noted that in the polarizing plate 513, the transparent substrate 581, the polarizing sub-layer 540, and the transparent substrate 583 can be formed first. The compensation film 530 is externally attached, so the compensation film 530 is externally attached, and the external compensation film 520 is also used in the polarizing plate 515. However, the implementation of the compensation films 520 and 530 is not limited thereto, and the polarizing plate 515 is used. For example, the modular structure can also be changed. The transparent substrate 585, the polarizing sub-layer 550 and the compensation film 520 are formed (the transparent substrate 587 is omitted), and the compensation film 520 is built-in. 1271589 (the amendment to the specification of the patent application No. 093 128120) and its compensation The film 520, 530 may be, for example, an anisotropic optical compensation film coated with a discotic liquid crystal having an oblique alignment. The additional functional film 56 may be composed of a single layer or a plurality of layers, for example, the additional functional film 56 is a single - a hardened layer or a single anti-glare layer or a single anti-reflective layer. The additional functional film 560 may also be a multi-layer function - stacked, if the additional functional film 560 and the polarizing sub-layer 55 〇 fit surface, for example, in order There are hardened layer, anti-glare layer and anti-reflective layer or low-reflection layer. Please refer to Figure 7. Figure 7 shows the schematic diagram of the liquid crystal alignment structure of the material source through the daily inspection. When the light source is injected by the polarizing plate 513 Since the direction of the polarized light of the polarizing plate 513 is the same as the direction in which the liquid crystal alignment film 501 is aligned, the liquid crystal alignment film 5(1) can sufficiently collect the light source. When the light source is emitted from the liquid crystal alignment film 5〇 through the liquid crystal alignment film 5〇3, Also due to The direction of the crystal alignment film 503 S is the same as the direction in which the polarizing plate 515 polarizes the light, so that the light source can be easily emitted from the liquid crystal alignment film 503 through the polarizing plate 515. Further, the compensation film 52 〇, 53 犯 is made by using the polarizing plate. It is possible to amplify the viewing angle of the light source. Therefore, through the liquid crystal alignment structure of the present invention, the viewing angle of the display of the twisted nematic liquid crystal display is expanded at 9 degrees and (10) degrees, and the angle of view of the polarizing plate is further increased.
