Description of the invention (8) The following will refer to the attached drawings to explain the details of the present invention in detail through preferred embodiments. ^ FIG. 1 shows a front view tree for explaining an embodiment of a liquid crystal display having a conductive pillar according to the present invention, and an f-plane view in the direction A-A ,. Please refer to FIG. 1 (a) and FIG. 1 (b). The liquid crystal display (100) is formed by a display area (20) formed in a pair of transparent substrates (10a, 10b). , And a sealing line (30) formed on the edge of the transparent substrate. A pixel electrode (1 丨), a thin film transistor (not shown in the figure) and a switching element are formed in a lower substrate (i0b) of a pair of transparent substrates. One is opposite to the pixel electrode (11). The electrode (〇pp〇site eiectrode) (13) is formed in the upper substrate (10a). By forming the pixel electrode and the counter electrode, the electric field will be injected into the pair and the substrate (10a, l) will be changed. 〇b) The arrangement of liquid crystals between them can cut or transmit light to display images. The electrode used in the display area (20) can be indium tin oxide (indium 〇xlde), and can also use a twisted nematic type (Twist TIO liquid crystal. The area of the sealing line (30) is where the dense sealing material (35) is applied.) Ding Bianyue In the present invention, a cylindrical or other shaped conductive post is formed in the display (20 ) And ^ seal area (30), so that the cell gap is in the liquid crystal display and the same specific distance 保持. Keeping the cell gap with the same specific distance 2 = because the pixel is filled with liquid crystal to maintain normal Optical center diameter. The V electric column (50) has a conductivity like The conductive material of the polymer compound allows the upper substrate (10a) and the lower substrate (10b) to be in electrical contact. The height of Lei's is the same as or higher than that between units, or it is higher than between units: Amendment 1226496 _ Case No. 92100302 5 Explanation of the invention (9) One point, the conductive pillars are completely adhered to the upper substrate and the lower substrate. (30) Formed on the edges of the transparent substrates (10a, 10b), and at small intervals, the composition is used to inject AT liquid crystal The liquid crystal injection hole (2 5). To perform an air removal process to remove air bubbles generated when liquid crystal is injected at a non-uniform velocity through the liquid crystal injection (2 5). Perform this process in the liquid crystal injection hole (2 5) In the process, a layer is formed to uniformize (eve η) the liquid crystal injection rate. Therefore, the air bubbles generated by not injecting liquid crystal can be avoided. However, this method requires a treatment, and the liquid crystal injection hole is formed after the base substrate is pasted. In order to omit this treatment, a guide (50) for maintaining the cell gap is also formed in the place where the input hole is formed to avoid air bubbles during the liquid crystal injection. In the liquid crystal injection (25) The shaped conductive pillar (50) can be injected at a normal speed to avoid the generation of air bubbles, and after the liquid crystal is injected, it is convenient to inject the holes. By depositing a conductive substrate on the transparent substrate (10a, 10b), A conductive pillar (50) is formed from the composite, and then photo-etching with a photoresistor is used. The conductor (50) makes the upper substrate and the lower substrate conductive. In addition, by making the pillar (50): The pair of transparent substrates (10a, 10b) can be brought into contact with each other. By doping a conductive material, polymerization can be performed in the conventional art, and the spherical spacer When the board is placed on the gap between the units, it is like an epoxy resin to fix the position of the partition. In this example, when the display area is pressurized, it will be applied to the sealing line. The large hole is generally required. In order to avoid the level, the same speed plate and the lower liquid crystal injection column are used. Composites, to 雉 to the separator crystal and 1226496

Description of the invention (10) When heat is generated, the epoxy resin will deteriorate and pollute the liquid crystal. Pollutants will reduce the resistivity of the liquid crystal (1 ^ to 31: ^ 11 ^), and reduce the electrical stress applied to both ends of the liquid crystal, which will affect the capacity and reliability. The conductive pillar (50) is formed by a photolithography process without using an adhesive in the step of manufacturing a transparent substrate. Therefore, the problem that the liquid crystal is contaminated and deteriorated can be avoided. The conductive pillars (50) arranged in the display area (20) can be arranged at the intersections between the pixel intervals, and the number can be smaller than the number of pixels corresponding to each pixel of the liquid crystal display. At the same time, the conductive post (50) can also be formed in the sealing line (30), where only the sealing material on the edge of the liquid crystal display (100) is applied: if necessary, the conductive post placed in the sealing line (30) The diameter of (50) may also be larger than the diameter of the conductive pillars of Anhuang in the display area.

The pixel electrodes (11) deposited on the lower substrate (10b) are separated by conductive pillars (50), and the opposite electrode (13) deposited on the upper substrate (10a) is in contact with the conductive pillars (50). Therefore, a voltage of 7 volts is applied to the pixel electrode (1 丨) and a voltage of 2 volts is applied to the conductive pillar (50). When a pixel is turned on, a voltage of 2 volts is applied to the opposite electrode of the upper substrate (10a) ( 13), so 5 volts will be generated between the counter electrode (1 3) of the upper substrate (10a) and the pixel electrode (丨!)

By depositing a conductive polymer compound on a transparent substrate and photolithography using a photomask (ph0t0 mask), the conductive post (50) is formed, and more specifically, a minute pattern photomask (minute pattern) can be used. mask), so that the conductive pillar (50) has a relatively small width. Alternatively, the conductive pillars (50) may be formed outside the transparent substrates (10a, 10b) using an adhesive. The conductive pillar (50) may also be formed in the liquid crystal injection hole. After the conductive pillar (50) is formed, a rubbing process may be performed. In the second step (ST 110), a thermosetting or ultraviolet setting epoxy resin is injected into the sealing area (30). At this time, since the conductive pillar (50) can maintain the cell gap, it is not necessary to inject the epoxy resin (70) and the spacer compound. Therefore: I to omit the process of removing air bubbles generated when the epoxy resin (70) and the partition are mixed. At this time, the sealing line or the sealing area prevents the epoxy resin (70) from being applied to the place where the liquid crystal injection hole is formed. l〇637pifi.ptc page 16 case number 92100302 1226496
