【発明の詳細な説明】 〔産業上の利用分野〕 本発明は液晶表示素子の製造方法に関し、特に、製造工程中のガラス基板における静電気の発生を防止する方法に関する。 DETAILED DESCRIPTION OF THE INVENTION The present invention [relates] relates to a method of manufacturing a liquid crystal display device, and more particularly, to a method for preventing the generation of static electricity in the glass substrate during the manufacturing process.

〔従来の技術〕 [Prior art]

従来、液晶表示素子を製造するには、まず、第5図に示す如く、金属製の機械ベッド6に載置されたガラス基板4上に、透明導電膜3を蒸着し、任意のパターにエッチングした後、液晶分子を配向させる高分子配向膜2を塗布する。 Conventionally, to manufacture a liquid crystal display device, first, as shown in FIG. 5, on the glass substrate 4 placed on the metal of the machine bed 6, depositing a transparent conductive film 3, the etching any putter after, applying an oriented polymer film 2 for aligning liquid crystal molecules. 次にこの高分子配向膜2を液晶分子を一定方向に並べるために、ポリエステル、ナイロン等の化学繊維でラビングする。 Next, in order to align the polymer alignment film 2 of the liquid crystal molecules in a certain direction, polyesters, rubbed with chemical fibers such as nylon. ラビングした後、外周シール材をガラス基板4上に印刷し、上記と同様に、透明導電膜3および高分子配向膜2を形成したガラス基板を第5図に示すガラス基板4に重ね合わせ、両ガラス基板を接着する。 After rubbing, the peripheral sealing material was printed on a glass substrate 4, similarly to the above, superimposed glass substrate with the transparent conductive film 3 and the polymer alignment film 2 on the glass substrate 4 shown in FIG. 5, both to bond the glass substrate.
その後、両ガラス基板で囲まれた空間に液晶を内部に注入する。 Thereafter, liquid crystal is injected therein in a space surrounded by the two glass substrates.

〔発明が解決しようとする問題点〕 [Problems to be Solved by the Invention]

上記従来の工程では、高分子配向膜2をラビングする際、絶縁体であるガラス基板4にはマイナス電荷が発生するため、次に次工程でガラス基板4を移す為に機械ベッド6から取り上げた時に静電誘導効果により−10数KV In the above conventional process, when rubbed polymer alignment film 2, the glass substrate 4, which is an insulator for a negative charge is generated, then it picked up from the machine bed 6 to move the glass substrate 4 in the next step by sometimes electrostatic induction effect -10 number KV
に帯電したガラス基板4から、機械のベッド6、作業者の手に放電が行なわれる。 Charged from the glass substrate 4, the machine bed 6, is discharged to the operator's hand is performed. またこの放電の際に、第6図に示す如く透明導電膜3であるセグメント電極3A、3Bがもっとも近接している箇所でも沿面放電が発生し、この放電によって、高分子配向膜2がダメージを受け、液晶の配向不良を発生させる可能性があった。 Further, when the discharge segment electrodes 3A is a transparent conductive film 3 as shown in FIG. 6, 3B creeping discharge is generated even at the location of the closest, by the discharge, the damage oriented polymer film 2 received, there is a possibility to generate a defective orientation of liquid crystal.

本発明は、上記のような、液晶表示素子の製造工程中において、素子に静電気が発生することを防止するためになされたものである。 The present invention, as described above, during the manufacturing process of the liquid crystal display device, has been made in order to prevent the static electricity is generated in the element.

〔問題点を解決するための手段〕 [Means for Solving the Problems]

そこで本発明では、2枚のガラス基板上に、透明導電膜および、配向膜を設け、この配向膜をラビング処理した後、前記2枚のガラス基板で囲まれる空間内に液晶を注入してなる液晶表示素子の製造方法において、 前記ラビング処理の前に、前記ガラス基板の外周に導電部材を形成するという技術手段を採用する。 Therefore, in the present invention, on the two glass substrates, a transparent conductive film and provided an alignment film, after rubbed alignment film, formed by injecting a liquid crystal into the space enclosed by the two glass substrates the manufacturing method of the liquid crystal display element, prior to the rubbing treatment, employing the technical means of forming a conductive member on the outer periphery of the glass substrate.

〔実施例〕 〔Example〕

以下本発明を図に示す実施例によって詳細に説明する。 The present invention will be described examples in detail shown in FIG.

本実施例では、第1図および第2図に示す如く、ラビング処理を行なう前に、ガラス基板4の外周に外周導電膜 In this embodiment, as shown in FIGS. 1 and 2, before performing the rubbing treatment, the outer peripheral conductive film on the outer periphery of the glass substrate 4
30を形成することを特徴とする。 And forming a 30. 具体的には、透明導電膜3をフォトガラス基板4に蒸着する際に、同時形成することが好ましい。 More specifically, when depositing the transparent conductive film 3 to the photo glass substrate 4, it is preferable to simultaneously form. つまり、フォトマスクに、透明導電膜3のパターンと外周導電膜30のパターンをそれぞれ形成しておけば、透明導電膜3の蒸着と同時に外周導電膜 That is, the photo mask, by forming the pattern of the pattern and the outer conductive film 30 of the transparent conductive film 3, respectively, at the same time the outer peripheral conductive film and the deposition of the transparent conductive film 3
30の蒸着がなされる。 Deposition of 30 is made. したがって、従来の製造工程に比べ工程数が増えることなく、極めて実用的である。 Accordingly, without the number of steps is increased compared with the conventional manufacturing process, it is very practical.

なお第1図において第5図および第6図と同一符号は、 Note the same reference numerals as FIG. 5 and FIG. 6 in the first figure,
同一構成物を示すため、これらの説明は省略する。 To show the same arrangement, descriptions thereof will be omitted.

上記外周導電膜30を蒸着した後には、従来と同じように、高分子配向膜2を塗布し、ラビング処理を行った後、ガラス基板4を機械ベッドから取りはずす。 After depositing the outer peripheral conductive film 30, like the prior art, the polymer alignment film 2 is applied and after the rubbing treatment, removing the glass substrate 4 from the machine bed.

この時ガラス基板4と機械ベッドとの間に放電が生じるが、ガラス基板4の外周には、外周導電膜30が設けられているため、放電は、機械ベッド6に最も近接した外周導電膜30の部分で発生し、透明導電膜3の部分で放電が発生することが確実に防止でき、表示部分の高分子配向膜2が放電によるダメージを受けることが防止できる。 Although discharge between the time the glass substrate 4 and the machine bed arise, since the outer periphery of the glass substrate 4, the outer peripheral conductive film 30 is provided, the discharge is the outer peripheral conductive film 30 closest to the machine bed 6 in generated in portions, the transparent conductive film 3 part can reliably prevent the discharge is generated, and it is possible to prevent polymer alignment film 2 of the display part is damaged due to discharge.

次に、ラビング処理が終わり、塵埃等を除去した後には、第3図に示す如く、エポキシ樹脂等からなる外周シール剤7を、スクリーン印刷によってガラス基板4に形成する。 Then, the end rubbing treatment, after removal of the dust or the like, as shown in Figure 3, the peripheral sealing material 7 made of epoxy resin or the like is formed on the glass substrate 4 by screen printing. この場合も、ガラス基板4の外周には外周導電膜30が設けられているため、スクリーン印刷したガラス基板4をスクリーン印刷機ベッドから取りはずす時、静電気は、ガラス基板4の外周導電膜30を通して、スクリーン印刷機の支持ベッド11に流れるため、高分子配向膜2の損傷が確実に防止される。 Again, since the outer periphery of the glass substrate 4 is outer peripheral conductive film 30 is provided, when removing the glass substrate 4 was screen printed from a screen printing machine bed, static electricity, through the outer peripheral conductive film 30 of the glass substrate 4, to flow to the support bed 11 of the screen printing machine, damage to the oriented polymer film 2 is reliably prevented.

次に、上記と同様に、透明電極3および高分子配向膜2 Then, similarly to the above, the transparent electrode 3 and the oriented polymer film 2
が形成されたガラス基板4を用意し、この2つのガラス基板4を第4図に示す如く外周シール材7を介して対向させて重ね合わせ、加圧および加熱処理することにより接着する。 There was prepared a glass substrate 4 formed, overlay the two glass substrates 4 are opposed to each other via a peripheral sealing material 7 as shown in Figure 4, to adhere by pressure and heat treatment. この後、両ガラス基板4で囲まれた空間内にフェニールシクロヘキサン系の液晶を充填し密封する。 Thereafter, filling the liquid crystal of phenylalanine cyclohexane system sealed in a space surrounded by the glass substrates 4.

〔発明の効果〕 〔Effect of the invention〕

以上述べたように本発明によれば、透明導電膜部分での沿面放電の発生が、確実に防止できるため、配向膜破壊による液晶の配向不良を確実に防ぐことができ、製品の品質を向上させ、信頼性を高めることができる。 According to the present invention as mentioned above, the generation of creeping discharge on the transparent conductive film portion, it is possible to reliably prevent, can be reliably prevented liquid crystal orientation defect due to the alignment film breakdown, improve product quality are allowed, it is possible to improve the reliability.
