Description of the Invention (1) Technical Field The present invention relates to a liquid crystal display panel and a method for manufacturing the same, and more particularly to a manufacturing technique when a rubbing treatment is performed on an inner surface of a liquid crystal panel substrate. BACKGROUND ART In the conventional technology, when forming a liquid crystal display panel, a transparent electrode made of ITO (indium, tin oxide) is formed on each of the pixels in the liquid crystal display area on the inner surface of a glass liquid crystal panel substrate. In the region, the lead-out wiring connected to the transparent electrode is led out of the liquid crystal display area, and the external connection terminals connected to the front end portion of the lead-out wiring are arranged to form an external connection terminal portion. On the other hand, in the liquid crystal display region, an alignment film is formed by printing with a resin such as polyimide or polyvinyl alcohol. This alignment film is subjected to a rubbing treatment described later. A transparent electrode is also formed on the inner surface of the other liquid crystal panel substrate, and a color filter is formed on the transparent electrode. The surface of the color filter is covered with a protective film made of transparent resin, and then the same alignment film is formed as described above and then subjected to rubbing treatment. Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) ) The two liquid crystal panel substrates thus formed are bonded by forming a seal # surrounding the liquid crystal display area, and then, the liquid crystal enclosed area surrounded by the sealing material is filled with liquid crystal. The cross-sectional structure of the liquid crystal panel substrate is shown in FIGS. 5 and 6, and the planar structure is shown in FIG. 7. 6 and 7 show a liquid crystal panel substrate 10 having a transparent electrode 11 formed on the surface, a lead-out wiring 18, an external connection terminal 12 and an alignment film 14. The paper size of this LCD panel substrate applies the Chinese National Standard (CNS) A4 specification (210X297 mm) _ 4-1229221, A7 ___'_ B7_ V. Description of the invention (2) A transparent electrode 11 is formed on the surface of 1 0, which leads out When wiring 18, external connection terminals 12, and alignment film 14 are subjected to a rubbing treatment, the friction roller 15 with a plush cloth (friction cloth) wound around the peripheral surface is rotated as shown in Fig. 7 The surface of the liquid crystal panel substrate 10 is rubbed diagonally. By the hairs 159 formed on the surface of the friction roller, many minute grooves are formed on the surface of the alignment film 14. When the liquid crystal contacts the surface of the alignment film 14, the liquid crystal molecules in contact with the grooves become aligned in the direction in which the grooves are formed. However, in the conventional friction treatment, as shown in Fig. 7, a part of the friction roller 15 is in contact with the external connection terminal portion 13 or the lead wire is printed. Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read first Note on the back side, please fill in this page again) 1 8 surface, so the hair of the friction roller 1 5 a abuts on the external connection terminal 1 or the lead wire 1 8 formed on the external connection terminal portion 13, as shown in FIG. 6 As shown in the figure, attachments 1 5 b such as shavings 15 a of the hair end of the friction roller or shavings of the alignment film 14 are removed by the side wall of the external connection terminal 12 or the lead-out wiring 18. On the other hand, the attached parts 15 b of the surface portion of the friction roller 15 which has not touched the external connection terminal 13 or the lead-out wiring 18 have not been removed. Therefore, among the surfaces of the alignment film 14 that are in contact with the surface of the friction roller 15, the adhesion of the adherends 15 b in the area A shown in FIG. 7 is reduced, and the alignment film in the area B shown in FIG. 7 is relatively small. There are many 1 5 b attachments on the surface of 1 4, and the friction state becomes spots as shown in the figure, causing a problem of uneven display in the liquid crystal display area. The present invention is to solve the above-mentioned problems, and an object thereof is to provide a liquid crystal display panel capable of preventing the uneven processing generated by the friction roller during the friction processing, reducing the uneven display of the liquid crystal display, and a manufacturing method thereof. This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) _ 5 _ 1229221 A7 B7 V. Description of the invention (3) Disclosure of the invention In order to solve the above problems, the liquid crystal display panel of the present invention has: The liquid crystal display area on the surface is provided with two liquid crystal panel substrates to which electrode patterns are applied; a liquid crystal layer disposed between the liquid crystal panel substrates; and connected to the inner surface of the liquid crystal panel substrate on at least one of the liquid crystal panel substrates. The applied electrode pattern lead-out wiring and / or an external connection terminal portion connected to the lead-out wiring; used to cover a peripheral portion of the liquid crystal display area including at least a portion of the lead-out wiring and / or the external connection terminal portion, and may An insulating film that reduces surface friction; and an alignment film that covers the liquid crystal display region. According to the present invention, at least a part of the lead-out wiring and / or the external connection terminal portion around the liquid crystal display area is covered with an insulating layer, and the surface friction of the covered portion is reduced, which can reduce the occurrence of contact with the lead-out wiring or the external connection terminal portion. The unevenness of the rubbing treatment on the alignment film can reduce the unevenness of the liquid crystal display panel. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). The surface friction of the insulation layer can be lower than that of the lead wires or the external connection terminals. This can reduce the friction treatment. The influence of the used member (friction roller, etc.) on the surface of the alignment film. In addition, the insulating layer and the alignment film may be formed to overlap each other, or may be formed to completely overlap as described later, or may be partially overlapped. In particular, when the insulating film is made of acrylic resin, it is easier to form a transparent film with acrylic resin, and the paper size with low surface friction is applicable to China National Standard (CNS) A4 specification (210X297 mm) ) 6 " 1229221 A7 B7 5. Description of the invention (4) Insulation film. In this case, if the thickness of the insulating film is 100 to 2 0 A, even if the insulating film is formed of an acrylic resin with low surface friction, the thickness of the insulating film is not easily reduced due to the thin thickness, so that the liquid crystal can be prevented. Display panel peeling. In addition, when a color filter is formed on the inner surface of one of the liquid crystal panel substrates, and when the insulating film is coated as a surface protective film of the color filter, an insulating film that also serves as a color filter protective film can prevent frictional treatment. Non-uniform, restrain the increase of the number of processes. In addition, when a color filter is formed on the inner surface of the liquid crystal panel substrate on the other side, and when the insulating film is used as a protective film on the surface of the color filter, the insulating film that also serves as a protective film for the color filter can prevent frictional processing. Non-uniform, restrain the increase of the number of processes. In addition, the surface of the insulating film surrounding the alignment film formed on the inner surface of the other liquid crystal panel substrate has less surface friction, and can be processed with early friction. At the same time, it can be made of the same material as the insulating film of one liquid crystal panel substrate. The protective film of the color filter is formed, the material management is easy, and the increase in manufacturing cost can be suppressed. Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) The manufacturing method of the liquid crystal display panel has the following steps: that is, between two liquid crystal panel substrates with a liquid crystal layer A step of forming lead wires and / or external connection terminal portions connected to the application electrode pattern formed on the liquid crystal display region on the inner surface of at least one of the liquid crystal panel substrates; and forming a coating including the lead wires and / or external connection terminals At least a part of the liquid crystal display area surrounding the above part of the liquid crystal display area to form an insulating film that can reduce surface friction, and to cover the liquid crystal display area of the alignment film steps. This paper is applicable to the national standard (CNS) A4 specification (210X297) (Centi) _ 7 _ '1229221 A7 B7 V. Description of the invention (5): and a step of applying a rubbing treatment to the inner surface of the liquid crystal panel substrate. In this case, if the insulating film and the alignment film are formed so as not to overlap each other, either of the insulating film and the alignment film may be formed first. (Please read the precautions on the back before filling in this page.) Here, after performing the above-mentioned steps of the rubbing treatment, there may be a step of removing the insulating film covering the external connection terminal portion. After the insulating film is formed on the entire inner surface of the liquid crystal panel substrate, the alignment film may be formed on the surface of the insulating film in the liquid crystal display region. In this case, because the insulating film is formed on the substrate of the liquid crystal panel, it is not necessary to choose formation or pattern wiring treatment. Therefore, it can be formed by a method such as a mandrel coating method and a small number of processes.

Finally, a film thickness of about 100 to 2 is formed. 〇 0A transparent insulation film 16. Next, a polyamido resin is coated on the liquid crystal display region on the surface of the transparent insulating film 16 and sintered to form an alignment film 14 having a thickness of 700 to 800 A. On the other hand, a transparent electrode 21 is formed on a liquid crystal display area on the inner surface of the liquid crystal panel substrate 20, and a color filter 2.2 is printed on the surface. On the surface of the color filter 22 and the entire surface including the outside of the liquid crystal display region, a transparent insulating film 23 having a thickness of about 200 A is formed by the same material as the transparent insulating film by a mandrel coating method. In the liquid crystal display region on the surface of the transparent insulating film 23, an alignment film of the same material as the above-mentioned alignment film 1 4 and having approximately the same thickness is formed.

As mentioned above, the LCD panel substrates 10 and 20 are formed on the inner surface. The rubbing treatment shown in FIG. 2 and FIG. 3 (the drawing shows the processing state of the liquid crystal panel substrate 10). There are various rubbing treatment methods. In this embodiment, a friction roller 15 having a surface having a large number of hairs 15 a is wound around a cylindrical roller. The friction roller 15 is pressed against the liquid crystal panel substrate 10 under a specific pressure, and the rotation direction of the surface system that is in contact with the liquid crystal panel substrate and the movement direction of the friction roller 15 are the same rotation direction while rotating. The inner surface of the liquid crystal panel substrate 10 is rubbed, and the rubbing roller is moved. The above-mentioned transparent insulating film 16 is formed relative to the external connection terminal 1 2 This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -9-1229221 A7 B7 V. Description of the invention (7) or lead-out wiring 1 8 The thickness is extremely thin, but the coating can ease the unevenness or convex shape existing on the surfaces of the external connection terminals 12 and the lead wires 18, and the transparent insulating film 16 is formed of an acrylic resin, so the surface friction is relatively high. Wiring 18 and external connection terminal 12 are low. Therefore, when friction is applied by the friction roller 15, no shaving of the hair 15a will occur between the hair 15a and the external connection terminal 12 or the lead-out wiring 18, or by the alignment film with the front section. If the contact, the swarf of the alignment film or the hair 15 a itself is generated, only the part contacting the external connection terminal 12 or the lead-out wiring 18 is removed by the side wall of the external connection terminal 12 or the lead-out wiring 18, As a result, the alignment film 14 in the liquid crystal display region can be subjected to a uniform rubbing treatment. With respect to the liquid crystal panel substrate 20, the above-mentioned rubbing treatment is applied to the liquid crystal panel substrate 10 in a direction orthogonal to the rubbing treatment direction applied to the liquid crystal panel substrate 10. The liquid crystal panel substrate 20 is also provided with a plurality of lead wires electrically connected to each of the plurality of transparent electrodes 21, and the lead wires are electrically connected to the above-mentioned external connection terminals 1 2 formed on the liquid crystal panel substrate 10. Economy Printed by the Consumer Standards Cooperative of the Ministry of Standards and Standards (please read the precautions on the back before filling this page). Next, align the LCD panel substrate 10 and the LCD panel substrate 20 as shown in Figure 1 to form an alignment film. The inner surfaces are facing each other, and a sealing material 30 formed of an ultraviolet hard resin or the like is bonded together. The sealing material 30 is formed in a frame shape as if it surrounds the liquid crystal display area, and the liquid crystal panel substrates 10 and 20 are bonded together to form a liquid crystal sealing area. A part of the sealing material 30 is left with a gap in advance to form a seal in the sealed area of the liquid crystal. The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm)-10-1229221 A7 B7. 5. Description of the invention (8) Finally, The liquid crystal 31 is injected through the sealed opening, and the sealed sealed opening 俾 forms a liquid crystal display panel holding a liquid crystal layer. After that, a part of the liquid crystal panel substrate is cut and removed to expose the external connection terminal portion, and the transparent insulating film 16 on the coated surface is removed by a plasma removing device or the like. When many transparent display sections are integrally formed, the respective liquid crystal display sections are cut and removed. In the above example, the external connection terminal portion 13 is formed only on the liquid crystal panel substrate 10, but in the liquid crystal panel substrate 20 without the external connection terminal portion, there is also a lead-out wiring at the outer edge portion of the liquid crystal display area, so it can be prevented Uneven friction caused by lead wiring. Here, no external connection terminal portion is provided on the liquid crystal panel substrate 10, and an external connection terminal portion may be formed on the liquid crystal panel substrate 20. Alternatively, external connection terminal portions may be provided on both the substrates 10 and 20. In this case, the transparent insulating films 16 and 23 are formed on any of the liquid crystal panel substrates 10 and 20, so that regardless of the external connection terminal portion formed on any of the substrates, the unevenness of the rubbing treatment of the alignment film can be prevented in the same manner as in the above case. . Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). The transparent insulating films 16, 23 are not limited to the above materials as long as the surface friction is lower than that of the external terminal section 13. When manufacturing a liquid crystal panel constituting a reflective liquid crystal display, a non-transparent insulating film may be formed on a reflective substrate (particularly, a reflective electrode is formed instead of a transparent electrode). The thickness of the transparent insulating film is preferably 200 A or less in order to ensure the adhesion of the sealing material of the liquid crystal panel substrate 5 among the above materials. The thickness easily formed by the mandrel coating method is preferably 100 A or more. If the thickness of the transparent insulating film is more than 200 A, the adhesiveness is reduced, and there is a possibility that peeling between the substrates may occur in the liquid crystal panel. This paper size applies to Chinese National Standard (CNS) A4 (210X297 mm) -11 1229221 A7 B7 V. Description of the invention (9) Generally, the film with low surface friction and low adhesion. Therefore, when a film made of a different material is used in place of the transparent insulating film, reducing the thickness to improve the adhesion is significant in preventing peeling of the liquid crystal panel substrate. In the present invention, a film with a low surface friction is formed in particular, so even if the film is thinner than the thickness of the external connection terminal, it is effective in preventing unevenness in the rubbing treatment. On the other hand, the external terminal portion constituting the uneven shape is thinly covered. This improves the adhesion of the formed film itself to the substrate of the liquid crystal panel. The thickness of the formed film is preferably 5 to 50% of the thickness of the external terminal portion. In the manufacturing process of the conventional LCD panel. The display unevenness caused by the unevenness of the rubbing treatment is about 90%. In contrast, the liquid crystal manufactured by forming the thickness of the insulating film in the range of about 150 to 190A according to the embodiment described above. For panel substrates, the observable display unevenness caused by rubbing treatment has dropped sharply to less than 10%. Therefore, the yield rate in the manufacturing process is greatly improved, and the display quality is also greatly improved. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page). In the above embodiment, the transparent insulating film is applied to the entire inner surface of the liquid crystal panel substrate. However, in order to achieve the same effect, an insulating film may be formed around the liquid crystal display region including at least the lead-out wiring and the external terminal portion. In this case, because the alignment film is covered with a uniform insulating film, it is also possible to prevent unevenness in the rubbing treatment. Fig. 4 is an end face structure of a liquid crystal display panel of a different embodiment from the above. In this embodiment, the same portions as those in the previous embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted. In this embodiment, an external connection terminal 12 is provided at the front end of the lead-out wiring 18 connected to the transparent electrode 11, which is the same as the previous embodiment. However, only in the LCD display area and the lead-out wiring, the paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm)-12-1229221 A7 ____B7 _ V. Description of the invention (10) 1 8 An insulating film is formed on the 6 There is no insulation film formed on the external connection terminals 12, which is different. In this embodiment, by arranging the peripheral portion 16 a of the insulating film on the lead-out wiring 18, although the friction unevenness caused by the external connection terminal 12 cannot be prevented, it can be prevented from being connected more than the external connection terminal 12 The frictional unevenness caused by the lead-out wiring 18 formed in a portion close to the liquid crystal display area, and at the same time, it is not necessary to remove the insulating film on the external connection terminal 12, which is an advantage. As described above, the effect of the present invention is that the peripheral portion of the liquid crystal display region including at least one portion of the lead-out wiring or the external connection terminal can be covered by the insulating film. For example, printed with the above-mentioned transparent insulating film 16 and printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) 2 3 The same insulating film, as shown in Figure 4 only It may be formed on the lead-out wiring 18. Alternatively, for example, in the peripheral portion of the liquid crystal display region, only the external connection terminal 12 on the side where the rubbing treatment of the rubbing roller 15 shown in FIG. 2 is first performed (that is, the upper side of the liquid crystal display region in FIG. 2) or The lead wires 18 may be covered with an insulating film. This is because the lead wires 18 and the external connection terminals 12 formed on the lower side of the liquid crystal display area shown in FIG. 2 have no effect on the rubbing treatment of the rubbing roller 15 on the liquid crystal display area. Industrial utilization possibilities. As described above, according to the present invention, a portion of the lead-out wiring and / or external connection terminal portions around the liquid crystal display area is covered with an insulating layer, thereby reducing surface friction. The non-uniformity of friction treatment caused by contact can be reduced, and the paper size can be reduced.
