(57) [Abstract] [Purpose] In the conventional liquid crystal substrate, the seal electrode part that is laid across the seal part has uneven pitch. Therefore, a seal in which two liquid crystal substrates are mixed with a gap control material is used. When a material is adhered and a predetermined gap is maintained, a gap difference corresponding to the wall thickness of the seal electrode portion is generated and a hue difference is generated. [Structure] Between the seal electrode portions 3c disposed in the seal portion 2a and having a low density, a position where the seal electrode portion 3c disposed in the seal portion 2a has the highest density is formed. By using the liquid crystal substrate 1 in which the sacrificial electrodes 4 are arranged so as to have the same density, a gap difference is generated between the two liquid crystal substrates 1 by making the contact condition of the gap control material 6 with the liquid crystal substrate 1 uniform. To prevent the occurrence of a hue difference.

従来の液晶基板90の例を要部で示すものが図3であり、ガラス基板91の一 方の面には酸化金属などによる透明電極92が敷設され、この透明電極92はガ ラス基板91の表示面に対応する位置では例えばドットマトリックスなど表示に 対応する形状に敷設されて表示電極部92aとされ、前記ガラス基板91の外縁 部では駆動回路(図示は省略する)との接続を行うための規定ピッチとされた端 子電極部92bとされている。 An example of a conventional liquid crystal substrate 90 is shown in FIG. 3, and a transparent electrode 92 made of metal oxide or the like is laid on one surface of a glass substrate 91. The transparent electrode 92 is formed on the glass substrate 91.

【課題を解決するための手段】[Means for Solving the Problems]

本考案は前記した従来の課題を解決するための具体的手段として、ガラス基板 のシール部を横切るようにして透明電極のシール電極部が配設され、前記シール 電極部の配設の密度に粗密を生じている液晶基板において、前記シール部に配設 される密度が粗となる前記シール電極部の間には、前記シール部に配設される前 記シール電極部の最も密度が密となる位置と略同一密度となるように捨て電極が 配設されていることを特徴とする液晶基板を提供することで、液晶基板の接合時 にギャップ差を生ずることのないものとして、前記した従来の課題を解決するも のである。 As a concrete means for solving the above-mentioned conventional problems, the present invention is such that the seal electrode portion of the transparent electrode is arranged so as to cross the seal portion of the glass substrate, and the density of the arrangement of the seal electrode portion is rough.

【実施例】【Example】

つぎに、本考案を図に示す一実施例に基づいて詳細に説明する。 図1に符号1で示すものは本考案に係る液晶基板の要部であり、この液晶基板 1はガラス基板2上の一方の面に透明電極3が敷設されたものであり、前記透明 電極3はガラス基板2の中心部では例えばドットマトリックス状の表示電極部3 aとして敷設され、外縁部では所定ピッチとされた端子電極部3bとして敷設さ れ、同時に前記ガラス基板2のシール部2aに対応する部分で斜行させられるな どして前記表示電極部3aと端子電極部3bの夫々に対応するものを接続するシ ール電極部3cとして敷設され、これにより前記シール電極部の配設の密度に粗 密を生ずるものとなっている点は従来例のものと同様であるが、本考案により前 記シール部2aのシール電極部3cが粗と成る部分のシール電極部3c間には捨 て電極4が配設されるものとなっている。 Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 is a main part of a liquid crystal substrate according to the present invention. The liquid crystal substrate 1 is a glass substrate 2 having a transparent electrode 3 laid on one surface thereof. Is laid in the center of the glass substrate 2 as, for example, a dot matrix-shaped display electrode portion 3a, and is laid as a terminal electrode portion 3b with a predetermined pitch in the outer edge portion, and at the same time corresponds to the seal portion 2a of the glass substrate 2. It is laid as a seal electrode portion 3c connecting the corresponding ones of the display electrode portion 3a and the terminal electrode portion 3b such that the seal electrode portion 3a and the display electrode portion 3b are slanted. The density is similar to that of the conventional example, but the present invention contemplates that the seal electrode portion 3c of the seal portion 2a is disposed between the seal electrode portions 3c which are rough. Electrode 4 It has become what is.

【0008】 以下に前記捨て電極4について更に詳細に説明を行えば、この捨て電極4は前 記ガラス基板2のシール部2aの範囲であり後にも説明するシール材5により他 の液晶基板との接着が行われる部分に配設されるものであり、且つ電気的に何れ の部分に接続されることもないものであり、その配設のピッチの基準としては前 記シール部2aにおけるシール電極部3cの最も密度が密である部分と略同一の 密度となるように配設されるものである。The waste electrode 4 will be described in more detail below. The waste electrode 4 is in the range of the seal portion 2a of the glass substrate 2 and is separated from other liquid crystal substrates by the sealing material 5 which will be described later. The seal electrode portion is disposed in a portion to be bonded and is not electrically connected to any portion, and the pitch of the arrangement is determined based on the seal electrode portion in the seal portion 2a. 3c is arranged so as to have substantially the same density as the densest portion of 3c.

【0009】 ここで、前記捨て電極4はシール電極部3cと同一の膜厚を有していることが 好ましく、よって前記捨て電極4の配設手段としては、前記透明電極3、即ち、 表示電極部3a、端子電極部3b及びシール電極部3cを敷設するときのフォト マスクに捨て電極4形成用のマスクを一体のパターンとして形成しておくことが 好ましく、また、このように一体に形成しておくことで、前記透明電極3の敷設 と同時に前記捨て電極4も同時に形成されるものとなり、この捨て電極4を形成 するための特別な工程の追加も生じないものとなるので一層に好都合である。Here, it is preferable that the discard electrode 4 has the same film thickness as that of the seal electrode portion 3c. Therefore, as the disposing means of the discard electrode 4, the transparent electrode 3, that is, the display electrode is used. It is preferable that a mask for forming the discarding electrode 4 is formed as an integral pattern on the photomask used when the portion 3a, the terminal electrode portion 3b, and the seal electrode portion 3c are laid, and is also formed integrally as described above. This is more convenient because the disposal electrode 4 is simultaneously formed at the same time as the transparent electrode 3 is laid, and no special process for forming the disposal electrode 4 is added. .

【0010】 図2に示すものは上記の構成とした本考案の液晶基板1の作用及び効果につい て説明を行うものであり、前記した表示電極部3aと端子電極部3bとの相互の 位置関係により配設のピッチに粗密を生ずるものとなるシール電極部3cに対し 、捨て電極4を粗となる部分に適宜に配置することで可能な限りに均等ピッチの ものとして、シール材5中に混和される例えばガラス球などによるギャップコン トロール材6に対する接触条件をシール部2aの範囲において均等なものとする のである。FIG. 2 illustrates the operation and effect of the liquid crystal substrate 1 of the present invention having the above-described configuration, and the positional relationship between the display electrode portion 3a and the terminal electrode portion 3b described above. With the seal electrode portion 3c that causes the pitch of the arrangement to become coarse and dense, by appropriately disposing the discarding electrode 4 in the rough portion, it is possible to mix the seal electrode 5 with the seal electrode 5 so that the pitch is as uniform as possible. The contact condition with the gap control material 6 by, for example, a glass ball is made uniform in the range of the seal portion 2a.

【0011】 このことは即ち、従来例でも説明したように二枚の液晶基板1を対峙した状態 で接着するときにも、シール電極部3cの有無による両液晶基板1間の間隔差は 生ずることのないものとなり、よって、完成後の液晶表示素子面での色相差の発 生が防止されるものとなる。This means that even when the two liquid crystal substrates 1 are adhered in a state of facing each other, as described in the conventional example, a gap difference between the liquid crystal substrates 1 due to the presence or absence of the seal electrode portion 3c occurs. Therefore, the occurrence of a hue difference on the surface of the liquid crystal display element after completion is prevented.

【考案の効果】[Effect of the device]

以上に説明したように本考案により、シール部に配設されて密度が粗となるシ ール電極部の間には、前記シール部に配設されるシール電極部の最も密度が密と なる位置と略同一密度となるように捨て電極が配設されている液晶基板としたこ とで、二枚の液晶基板を前記シール部でギャップコントロール材を混和したシー ル材で接着し所定の間隔を保持させるときに、前記ギャップコントロール材の液 晶基板に対する接触条件を均一なものとして二枚の液晶基板間に間隔差を生じな いものとし、この間隔差に起因する液晶表示素子面の色相差の発生を防止し、こ の種の液晶表示素子の品質向上に優れた効果を奏するものである。 As described above, according to the present invention, between the seal electrode portions arranged in the seal portion and having a low density, the seal electrode portions arranged in the seal portion have the highest density. By using a liquid crystal substrate in which the discarding electrodes are arranged so that the density is approximately the same as the position, the two liquid crystal substrates are adhered with a seal material mixed with a gap control material at the seal part, and a predetermined gap is provided. When holding the gap control material, the contact condition of the gap control material with the liquid crystal substrate should be uniform so that there is no gap difference between the two liquid crystal substrates. It prevents the occurrence of a phase difference and has an excellent effect in improving the quality of this type of liquid crystal display device.
