Field of the Invention The present invention relates to the manufacture of liquid crystal displays, and more particularly to a nozzle assembly for a liquid crystal coating apparatus for applying liquid crystal onto a substrate. [Prior Art] In general, a flat panel display (FPD) is a lighter and thinner image display device than a television or monitor using a cathode ray tube. Such flat panel displays include liquid crystal displays (LCDs), plasma display panels (/PDPs), field emission displays (FEDs), organic light emitting diodes (OLEDs), and the like. ^ The liquid crystal display displays a desired image by supplying a data signal corresponding to the image information to the liquid crystal cell (edl), respectively, in the form of a cap crystal unit = matrix to adjust the light transmittance of the liquid crystal cell. The liquid crystal display is thin and light in weight, and has low power consumption and a low package [due to these advantages, the liquid crystal display is widely used. 6 200815108 Hereinafter, a method of manufacturing a liquid crystal panel commonly used in liquid crystal displays will be described. First, a color filter and a common electrode are formed in a pattern on the upper glass substrate. A thin film transistor (TFT) and a pixel electrode (pixeldectr) are formed in a pattern on the lower substrate of the upper light neon. Next, alignment 35 is formed on the upper glass substrate and the lower glass substrate, respectively, and then rubbing the alignment phase provides the surface and the fresh direction to the liquid crystal molecules of the liquid crystal layer formed between the alignment layers. In order to bridge the gap between the substrate and the lower glass substrate, prevent liquid crystal leakage, and seal the upper glass substrate and the lower glass substrate, Mina (4) is applied to the upper glass substrate and the lower glass plate. . The liquid crystal layer is formed between the glass substrates under the upper base to produce a liquid crystal panel. Here, in order to form a liquid crystal layer, a liquid crystal coating method can be used. The liquid crystal coating method is carried out by applying liquid crystal to a space defined by a sealant on a substrate to form a liquid crystal layer, then placing the substrates together and hardening the sealant to bond the substrates together . In order to form a liquid crystal layer by a liquid crystal coating method, a liquid crystal coating apparatus is used. While the nozzle is relatively moved with respect to the substrate, the liquid crystal coating apparatus forms a liquid crystal layer by applying liquid crystal from the squirting (liquid crystal supplied by the nozzle) onto the substrate. In the liquid crystal coating apparatus, since the liquid crystal has a high viscosity, the liquid crystal droplet remains on the tip end of the nozzle after the application of the elemental liquid crystal. 7 200815108 When the mouth moves, the liquid crystal droplets remaining on the tip of the nozzle may be secreted to the undesired position of the substrate. In order to avoid this problem, according to the conventional technique, a separate vacuum pressure generating device is provided to generate a vacuum pressure in the nozzle, and the liquid crystal remaining on the nozzle tip is sucked back into the nozzle. However, in the conventional art, the vacuum pressure generating device has a complicated structure since it is necessary to control the vacuum pressure to uniformly suck the liquid crystal droplets back into the nozzle. SUMMARY OF THE INVENTION The present invention provides a nozzle assembly for a liquid crystal coating apparatus, and the 'nozzle assembly has a structure of a single bill, and after the coating of the crystal is finished, the nozzle assembly can be used to touch the nozzle line. The upper crystal is sucked back into the nozzle. According to one aspect of the present invention, a nozzle assembly for a liquid crystal coating apparatus is provided, wherein a nozzle assembly includes: a nozzle for permitting crystallizing, and applying liquid crystal to the substrate when the nozzle is opposed to the substrate; and elastic The plate is disposed at a passage through which the crystal passes through the nozzle. The elastic plate has at least a slit and the miscellaneous plate is formed of a miscellaneous material, and the towel is elastically deformed when the discharge pressure acts on the liquid crystal, and the liquid crystal passes through the reading. To the J-face' and when no discharge pressure acts on the liquid crystal, the elastic plate returns to its original shape, thereby sucking the liquid crystal remaining on the lower portion of the elastic plate back into the upper space of the elastic plate. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described more fully hereinafter with reference to the accompanying drawings in which FIG. 1 is a perspective view of a nozzle group = 100 for a liquid crystal coating apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view of the elastic plate 120 of the nozzle assembly 1 (8) shown in the drawing. Referring to Figures 1 and 2, the nozzle assembly 1 includes a nozzle 11 被 which is included in a liquid crystal coating apparatus for forming a liquid crystal layer on a substrate by applying liquid crystal onto the substrate. The nozzle 110 accommodates a predetermined amount of liquid crystal and applies liquid crystal onto the substrate while moving relative to the substrate. There is a space ' inside the nozzle 110 and includes a nozzle tip ln at the lower end. The nozzle U0 accommodates liquid crystal from a syringe in which liquid crystal is stored. A valve is installed between the nozzle 11 〇 and the syringe. The valve controls the amount of liquid crystal supplied to the nozzle 110 such that the nozzle 110 can accommodate a predetermined amount of liquid crystal. Moreover, when the liquid crystal is supplied from the syringe to the nozzle 110 by opening or closing the valve, it is necessary to apply a discharge pressure to the liquid crystal in the main illuminating state to discharge the liquid from the nozzle 110. Here, the discharge pressure applied to the liquid crystal is supplied by a pump, a pneumatic feeder, or the like. Meanwhile, if the discharge pressure is applied to the liquid crystal by the pneumatic feeder, a valve for controlling the air supply between the pneumatic feeder and the injector can be used instead of using a valve for controlling the liquid crystal supply between the injector and the nozzle 110. After the liquid crystal is applied through the nozzle 110, since the liquid crystal has a high dryness, the liquid crystal droplet remains on the nozzle tip n1. When the nozzle 110 is moved, the liquid crystal droplet remaining on the nozzle tip ill may drip to an undesired position of the substrate and soil the substrate. To avoid this problem, the elastic plate 120 is formed in the nozzle 110 according to the current embodiment. The elastic plate 120 is formed of an elastic material having a predetermined thickness. Here, as shown in FIG. 2, the elastic plate 120 is formed in a disk shape corresponding to a nozzle n〇 = inner space having a circular cross section. Further, the elastic plate 12 protrudes in a dome shape in a direction in which the liquid crystal is supplied to the nozzle 110. Meanwhile, in addition to the structure shown by =2, the elastic plate 12G is incident as any structure which can be elastically deformed when the liquid crystal is applied to apply a discharge pressure to the liquid crystal. For example, the elastic plate 120 is formed in a flat plate shape. 200815108 The elastic plate 120 has at least one slit 121, and when the discharge pressure for the liquid crystal is transmitted to the elastic plate 120, the elastic plate 12 is elastically deformed, the liquid crystal passes through the at least one slit, and the liquid crystal is applied to the substrate. on. Here, the slits 121 may be a plurality of slits that intersect each other at the central portion of the elastic plate 12A. Preferably, 'each slit 121 has a predetermined width, when the elastic plate 12 is not elastically deformed, that is, before the liquid crystal is applied onto the substrate or after the coating of the liquid crystal is completed, the predetermined width Sufficient to prevent liquid crystal from leaking out of the elastic plate 120. Meanwhile, although two slits ΐ2ι are shown in Fig. 2, one, three, or a plurality of slits may be formed in the elastic plate 120. Further, it is preferable that the plurality of slits 121 are disposed at the same angle to each other. Therefore, when the elastic plate 120 is elastically deformed due to the discharge pressure acting on the liquid crystal and the width of the slit 121 is widened, the shape of the slit 121 becomes substantially circular, corresponding to the internal space of the nozzle tip U1. The circular cross section 'is as follows. Further, when the coating of the liquid crystal is completed, no discharge pressure f acts on the liquid crystal and is transmitted to the elastic plate 120, so that the elastic plate 12 is returned to its original shape. When the liquid remaining on the lower portion of the elastic plate 12 is passed to the upper portion (four) of the elastic plate 120, the plate (10) is uniformly transferred to the liquid crystal, so that the liquid crystal can be uniformly sucked back into the upper portion of the elastic plate. 11 200815108 The netness plate 120 is placed in the nozzle n〇 across the passage through which the liquid crystal flows. That is, the elastic plate 120 is mounted in the nozzle n〇 in such a manner that no liquid crystal flows through the remaining portion of the elastic plate 120 except the slit 121. The elastic plate 120 is mounted in the nozzle 11A so as to be movable up and down. The purpose of this structure is to restore the elastically deformed portion of the elastic plate 120 to its original shape and simultaneously move the elastic plate 12〇 upward when the application of the liquid crystal is completed so that the discharge pressure is no longer transmitted to the elastic plate 120. Enhance liquid crystal suction. For this operation, the support portion 122 may be additionally formed around the miscellaneous board 12(). The support portion 122 supports the elastic plate 12A such that the elastic plate 12 is stably slidably moved up and down along the inner wall of the nozzle no. Here, the support portion 122 has a tightly attachable to the nozzle 110 at the edge of the elastic plate 12G.

The downwardly moving P' protrusion of the elastic plate 12 is set to be separately manufactured for the Γ〇 and f-plates 120, and then the support portion is fixed to the same ground. The portion 122 can ensure long-term durability by the elastic plate. The body is made of 攸 and 200815108, when the discharge pressure is on the liquid crystal, the elastic plate 12 having the above structure is elastically deformed to pass the liquid crystal through the slit 121, and when there is no When the discharge pressure acts on the liquid crystal, the elastic plate returns to the original shape to suck the liquid crystal remaining on the lower portion of the elastic plate 120 back into the upper portion of the elastic plate 12A. That is, according to the embodiment, the liquid crystal is coated as in the embodiment. The liquid crystal droplets which may remain on the nozzle tip m after the cloth can be easily sucked back into the nozzle 110 by a simple structure. The following will be described with reference to Figs. 3A, 3B, and 3 (: The process will be described in detail. In Fig. 3B And 3C, for the convenience of description, only show The liquid crystal droplet remaining on the lower portion of the elastic plate 120. As shown in Fig. 3A, if the liquid crystal 1〇 is applied onto the substrate and a discharge pressure is applied from the upper space of the nozzle 110 to the liquid crystal 1 , the liquid crystal 10 is applied. The discharge pressure is transmitted to the elastic plate. Therefore, the elastic plate 120 is moved downward in accordance with the guide of the branch portion 122 until the projection 122a is hooked by the pawl 110a and elastically deformed. Therefore, the width of the slit 12i The liquid crystal 10 is widened by passing the liquid crystal 10 through the widened opening of the slit 121. After the coating of the liquid crystal 10 is completed, since the liquid crystal 10 has a high viscosity, the liquid crystal 10 remains in The lower portion of the elastic plate 120, that is, remains on the lower portion of the slit 121 as shown in Fig. 3B. At this time, since the application of the liquid crystal 10 has been completed, the discharge pressure is no longer applied to the elastic plate 120. 13 200815108 Therefore, as shown in Fig. 3C, the elastic plate 12 is returned to its original shape. That is, the elastic plate 120 is moved upward in accordance with the guiding of the support portion 122, and at the same time, the rotationally deformed portion of the elastic plate 120 is returned to its original shape. by Since the pressure is not applied to the crystal 10, the pressure acting on the elastic plate 120 is lowered, and the volume of the upper portion of the elastic plate 12 is reduced, so that the liquid crystal having a slightness remaining on the lower portion of the elastic plate 12G passes through the slit 121. And it is smoothly sucked back into the upper space of the elastic plate 12A. As described above, according to the present invention, the liquid crystal remaining on the nozzle tip can be easily sucked after the liquid crystal coating by the simple structure. Returning to the inside of the nozzle, therefore, unlike the conventional technique, since the separate vacuum pressure generating means for sucking the liquid crystal remaining on the nozzle tip back into the nozzle is not required, the structure of the liquid crystal coating apparatus can be simplified. Moreover, since the phenomenon that the liquid crystal droplets remain on the nozzle tip after the liquid crystal coating can be prevented, the problem that the liquid crystal drops to an undesired position of the substrate and smudges the substrate when the nozzle moves can be avoided. It is apparent to those skilled in the art that various modifications and changes can be made in the invention without departing from the spirit and scope of the invention. Therefore, the present invention is intended to cover such modifications and variations of the present invention as long as they are within the scope of the appended claims and their equivalents.
