The liquid crystal panel is an important component of the liquid crystal display in which the alignment film of the liquid crystal panel 'controls the predetermined initial state of the liquid crystal molecules of the liquid crystal layer' affects the display characteristics of the liquid crystal panel. [0003] Please refer to FIG. 1 for a schematic structural view of a prior art liquid crystal panel. The liquid crystal panel 100 includes two substrates 11 opposite to each other, a liquid crystal layer 120 sandwiched between the two substrates 110, and two alignment films 130. The two substrates 11 are respectively a color filter substrate and a thin film transistor substrate. The two alignment films are respectively disposed on the side of the two substrates 110 adjacent to the liquid crystal layer 120. The alignment film 130 is provided with a plurality of trenches 131 adjacent to the surface of the liquid crystal layer 120 for aligning the liquid crystal molecules of the liquid crystal layer 120. The trenches 1 31 are parallel to each other and uniformly arranged such that liquid crystal molecules adjacent to the alignment film 130 are aligned along the trenches 131.

Step 4: The alignment film 130 is frictionally aligned by a pointing device to form the plurality of grooves 131. Referring to Fig. 2, a schematic diagram of the formation of the trenches 1 31 of the alignment film 130 is shown. The device (not shown) includes a roller 1 and a base 12. The base 12 is used to carry the substrate 11 and is horizontally movable in the direction of the roller. The surface of the S-wheel 10 is covered with a layer of a wool cloth 11 . The roller rotates at a high speed around its own axis, and the base 12 drives the upper substrate; when the roller cloth is advanced in the u direction, the roller cloth 11 is in contact with the alignment film 13 of the base.
