[Prior Art] In general, a liquid crystal display (LCD) includes at least: a bottom or rear substrate of a flat glass plate provided with a driving element (for example, a transistor; a top of a flat glass plate or a front substrate provided with a color filter layer; a sealing material bonding the bottom substrate to the top substrate; and a liquid crystal layer formed between the bottom substrate and the substrate Between the top substrates, the liquid crystal molecules of the liquid crystal layer are redirected by the driving elements formed on the bottom substrate to control the amount of light penetrating through the liquid crystal layer, thereby displaying information.

For the method for manufacturing an LCD device, a substrate is prepared by forming a driving element on a glass plate of a specific size, and another substrate is formed by forming a color filter layer on another glass plate. preparation. Then, a sealing material is dropped onto one of the two substrates to have a pattern of a specific shape, and liquid crystal droplets are dropped into the pattern of the sealing material. Thereafter, the two substrates are joined to each other. The joined substrate is referred to as mother glass. Then, by cutting the mother glass, individual liquid crystal panels (each of which constitutes an LCD) can be manufactured.

1359970 The manufacturing process is performed on a production line where manufacturing equipment with different functions is provided. A process for dispersing the liquid crystal and a process for ejecting the sealing material are performed by a disperser in the manufacturing equipment. Figure 1 is a perspective view of an example of a disperser according to the prior art. Referring to Figure 1, the operation of the disperser will be described in terms of a process for dispersing the liquid crystal. .

First, a glass G is placed on a linear reciprocable platform 200 that is mounted on a frame 100. Next, the liquid crystal is dropped according to a predetermined pattern through a nozzle 310 constituting a head unit 300 (where the head unit 300 is mounted on the stage 200), and the liquid crystal system dropped through the nozzle 310 is patterned on the glass G to be predetermined. Shape (where the glass G is placed on the platform 200).

Since the head support member 400 is mounted on the frame 100, the nozzles 310 of the head unit 300 can be moved in a predetermined pattern to linearly reciprocate, and the head unit 3 00 mounted on the head support member 400 can linearly reciprocate. mobile. The direction in which the head support 400 moves is perpendicular to the direction in which the head unit 300 moves. The component symbol 50 indicates the guiding member, and the component symbol 600 indicates a fixed table. The glass G placed on the platform 200 of the disperser is attached to the platform 200 under a vacuum suction pressure to avoid the glass G moving on the platform during operation. Hereinafter, the structure for adhering the glass G to the platform 200 according to the prior art will be explained. Figures 2 and 3 are a top view and a front view, respectively, showing 6 1359970

A glass adhesion structure used in a disperser platform according to conventional techniques. The platform 200 for the disperser has a specific thickness and an area of 200. The upper surface is flat, and the glass G is placed on the flat upper surface. A plurality of main perforations 210 are formed in one of the platforms and have a specific interval. A plurality of small 220s in communication with the main perforations 210 are formed in the upper surface of the platform 200. Further, a plurality of vacuum inlets 230 communicating with the plurality of perforations 210 are formed in one of the platforms 200. Both ends of the main perforations 210 are hermetically sealed, and the plurality of 220 are formed along the main perforations 210. The vacuum inlet 230 is connected to an external vacuum generating unit (not shown) (e.g., a vacuum pump). We will explain the operation of the glass adhesion structure. When the glass G is placed on the table 200, the vacuum generating unit is operated to attract air. The amount of attraction of the raw unit is applied to the lower surface of the glass G via the vacuum inlet 230, the main perforation 2], and thus the high ambient pressure of the glass G is applied to the upper surface of the glass G to adhere to the upper surface of the platform. When the glass G to drop the liquid crystal to be fixed to the stage 200 is completed, the operation of the vacuum generating unit is stopped, and the amount of attraction of the glass G is removed. Therefore, the glass G is movably placed on the platform 200, whereby the glass G placed on the platform 200 is transported by an additional transfer robot (not shown) for use in the process. In the glass adhesion structure used for the diffuser platform, because it is flat. The platform table 200 is attached to the surface suction hole and the main lower surface suction hole to a flat vacuum production 0 and suction 200 is added to the glass to be placed on the surface of the next stage 200 7 1359970 As a plane, this contributes to the cleaning operation, and the amount of particles remaining on the platform after the cleaning operation is very small. However, this structure has the following drawbacks. Since the upper surface of the platform 200 is a flat surface, the contact area between the stage 200 and the glass G is wide, thereby causing a large amount of static electricity between the stage 200 and the glass G. Therefore, when the glass G is lifted by the transfer robot, cracks may be generated in the glass G, or the circuit or the color filter layer formed by the semiconductor process may be damaged due to high static charge.

In order to solve these problems, another glass adhesion structure for a disperser platform has been proposed according to the prior art, as shown in Fig. 4. Referring to FIG. 4, a plurality of grooves or channels 240 having a particular depth, width and length are formed in the upper surface of the platform 200, wherein the glass G is placed on the platform 200. The channel 240 has a square cross section. In this other conventional glass adhesion structure for a disperser platform, the amount of static electricity generated when the glass G is lifted from the platform 200 can be reduced. However, since the channel 240 having a square cross section is formed in the upper surface of the stage 200, it is difficult to perform the cleaning operation, and even after the cleaning operation, many fine particles may remain on the stage. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a glass adhesion structure for such a disperser platform that simplifies the cleaning operation and reduces the electrostatic generation when the glass is lifted from the platform.

The above and other objects, features, aspects and advantages of the present invention will become apparent from [Embodiment] The present invention will be described in detail, and examples of the invention are illustrated in the accompanying drawings. Referring to the accompanying drawings, a glass adhesion structure for a diffuser platform according to the present invention will be explained below. Fig. 5 and Fig. 6 are respectively a plan view and a front view, respectively, of a glass adhering structure for a diffuser ditch bag according to the present invention, which is in a state of approximating with a level of 9 1359970. As shown, the diffuser platform 700 has a particular thickness and area. A plurality of main perforations 710 are formed in one of the lateral surfaces of the platform 700 with a specific interval. A plurality of small suction holes 720 communicating with the main perforations 7 1 〇 are formed in the upper surface of the platform 700, wherein the upper surface is provided with the glass G.

An inclined channel 740 having a V-shaped cross section is formed in the upper surface of the platform 700 between adjacent columns of suction holes 720, each inclined channel 740 having two inclined surfaces 741. The inclined channels 740 extend between opposite side surfaces (e.g., front and rear) of the platform 700. The two inclined surfaces 741 constituting the inclined groove 740 are flat, and an angle formed between the inclined surfaces 741 is preferably an obtuse angle. The gap between the inclined channels 740 is preferably two to four times the inner diameter of the suction holes 720, wherein the inclined channels 740 are located on both sides of each of the columns of suction holes 720.

For another embodiment of the inclined channel 740, as shown in FIG. 7, the inclined groove 740' is constituted by two inclined surfaces 741' and a curved surface 742 formed on the inclined surfaces 741.
