Description

201017296. VI. Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display manufacturing method, and more particularly to a liquid crystal display substrate alignment processing method. [Prior Art] In the liquid crystal display process, two substrates are generally joined by a sealing material* and a liquid crystal (LC) material is injected into a small space between the two substrates. Next, polarizing films are attached to the outside of each of the substrates, and a driving electronic printed circuit board (PCB) is attached. Finally, the liquid crystal display is completed by adding a backlight unit. An alignment film is disposed on the liquid crystal display substrate to uniformly align the liquid crystal molecules between the two substrates. The step of forming an alignment film generally comprises coating a polyimide PI layer, pre-baking the poly-branched amine layer, heating and removing the solvent in the polyamidamine layer, and then solidifying the polyamidamine layer to make it sub- Deuteration forms a polymer material, and a polyimide layer. Among them, the conventional method of aligning the polyamidamine layer is rubbing, brushing the alignment film with a fleece cloth, or photo aligning with a linearly polarized UV light alignment film. However, the brushing process produces residual dust which requires cleaning equipment to be cleaned, thereby increasing process steps and costs. In addition, other undesired dents or scratches may occur during friction to reduce the yield, and electrostatic problems caused by friction may also cause damage to the circuit on the substrate. In addition, the conventional photo-alignment technique irradiates the alignment film with UV light of a specific polarization direction (for example, a direction of 45 degrees from the y-axis), so that the alignment film can perform a direction-selective photochemical reaction (only relevant to the y-axis direction). The photochemical reaction), in turn, causes the alignment film molecules to have a specific alignment direction, so that they have a film molecular solidification rate of 201017296 of less than or equal to 50%. In the region where the UV light is aligned in a specific polarization direction, the absorption film of the alignment film in the specific polarization direction (e.g., 45 degrees and 135 degrees in Fig. 6) has a reduced ability to absorb UV light. As shown in Fig. 6 (the vertical axis represents the absorption capacity of the alignment film, and the horizontal axis represents the polarization direction of the linearly polarized light that illuminates the alignment film with the y-axis angle). Furthermore, in the conventional optical alignment technique, if the alignment film is to have a plurality of alignment directions, it is necessary to use a photomask and expose the alignment films from different directions, so that the φ process is quite complicated. SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a novel liquid crystal display substrate alignment processing method which can overcome or ameliorate the problems of the aforementioned prior art. The liquid crystal display substrate alignment processing method according to the present invention mainly comprises forming an alignment film on a substrate, the alignment film comprising a plurality of solid molecules; applying an electric field to the substrate to rotate the solid molecules; and curing The curable molecules cure the curable molecules in a first direction. Compared with the conventional brushing treatment, the alignment treatment method of the present invention does not generate static electricity, and does not cause surface dents or scratches, thereby greatly increasing product yield; further, the alignment treatment method of the present invention does not Residual dust is generated, so the washing step can be omitted, thereby reducing the manufacturing cost. Compared with the conventional photo-alignment technology, the present invention utilizes electric field alignment to cure the alignment film material by UV light, so that the curing ratio can be greater than 50%, and even closer to ι〇〇〇/0, Because the invention utilizes electric field alignment, and the function of UV light only cures the alignment film material and the UV light is not 201017296. With a specific polarization direction, the alignment film molecules also have no directional selective polymerization, so when the alignment film completes the electric field alignment, The second uv light of different polarization states is given, #· and the difference of the UV light absorption spectrum of the two exposures is compared, and the absorption amount corresponding to the light of the polarization direction of the second UV is substantially equal.

When a predetermined voltage is applied, as shown in Fig. 2, the slit 112a of the pixel electrode 112 (electrode) An electric field (shown by a broken line in Fig. 2) is formed in the vicinity of the edge. The oblique electric field generated between the substrates determines the tilt direction of the liquid crystal molecules 140. In Fig. 2, the interlayer is placed. The orientation of the liquid crystal layer between the first substrate 110 and the second substrate 12 is divided into two different directions. Because of the affinity between the curable molecules and the liquid crystal molecules, each solidity is determined. The slanting direction of the adjacent liquid crystal molecules is obeyed, so the curable molecules in Fig. 2 can be divided into two groups having different tilt directions. The aforementioned curing step can be performed by a photocuring step (for example, irradiating ultraviolet light) Some of the curable molecules) or a thermal curing step (eg, heating the curable molecules) is achieved. After the energy is applied to cure the curable molecules 132, two adjacent curable molecules 132 having the same oblique direction react. Φ This cross-links (cross-1丨nked), as shown in Fig. 3, the reaction may be a cycloaddition reaction, or as shown in the seventh figure, the molecule may also be a functional group polymerization reaction. In one embodiment, the interconnected curable molecules 132 can align the alignment of the liquid crystal molecules 140 when no voltage is applied, thereby stabilizing the pretilt angle and alignment of the liquid crystal molecules 140. As shown in FIG. 4, the orientation of the liquid crystal The system is divided into two different directions, thereby obtaining a wide viewing angle. Compared with the conventional brushing treatment, the alignment treatment method of the present invention does not generate static electricity and does not cause surface dents or scratches. The product yield can be greatly increased by 26 201017296. In addition, the alignment treatment method of the present invention does not generate residual powder. The chips can therefore omit the cleaning step, thereby reducing the manufacturing cost. And compared with the conventional optical alignment technology, The invention utilizes electric field alignment to cure the alignment film material by UV light, so the curing ratio (匸(10) tons ratio) can be greater than 50%, and even approaches 100%, and the present invention utilizes electric field alignment, and the function of uv light Only the alignment film material is cured and the uv light does not have a specific polarization direction, and the alignment film molecules are also non-directionally polymerized. Therefore, when the alignment film completes the electric field alignment, the second uv light of different polarization states is given and compared twice. The exposed UV light absorbs the difference in the spectrum, and the amount of absorption corresponding to the light in the polarization direction of the second UV is substantially equal (see Fig. 5). Further, the aforementioned alignment film may be formed using the following composition, which mainly comprises a photo alignment material and a vertical alignment material.
