導電性の良い銀ペーストなどが多く採用されている。In recent years, liquid crystal display elements have been increasingly used as display devices because they are capable of displaying large areas with low power. These devices usually have a structure in which a liquid crystal is sandwiched between substrates provided with electrodes, and a driving device that applies a voltage to the electrodes is installed on a liquid crystal display cell in which the periphery of the liquid crystal is sealed with adhesive. The display pattern i is usually formed by applying a voltage to a desired electrode through an electrode terminal. Common and segment electrode terminals are often used as voltage application terminals, but most cells have common electrode terminals and segment electrode terminals using a transfer material to expand the effective display area, simplify terminal connections, and stabilize manufacturing conditions. Segment electrode terminals are gathered on one substrate such as a segment substrate. Silver paste, which has good conductivity, is often used as a material for forming the transfer material for this purpose.
[発明の解決しようとする課題]

表示エリアの大きさを損なわないこと等を考慮して、’
tFi晶表示セルの周辺シールの内部に、あるいは周辺
シールに接して設けることが多い。[Problems to be Solved by the Invention] The above-mentioned transfer has been developed in consideration of the stability of the transfer and the size of the display area.
It is often provided inside or in contact with the peripheral seal of a tFi crystal display cell.
このとき、従来用いられている液晶表示セルにおいては
、トランスファー材に近接するシール材として、前述の
ように有機系の接着剤や、あるいはフリットガラスを用
いることが多い。At this time, in conventionally used liquid crystal display cells, an organic adhesive or frit glass is often used as the sealing material close to the transfer material, as described above.
これらのシール材の色調は表示素子の見栄えを大きく左
右するため、なるべく表示の背景色に近い色調のものを
用いることが多い。Since the color tone of these sealants greatly affects the appearance of the display element, a color tone as close as possible to the background color of the display is often used.
例えば、ネガ型液晶表示素子においては、黒色を呈する
ものであり、ポジ型液晶表示素子においてはその背景の
白色やその他の色を呈するものである。For example, in a negative type liquid crystal display element, the color is black, and in a positive type liquid crystal display element, the background color is white or another color.

色調が異なり、やはり見栄えの良いものではない。However, in such a case, if conventional silver paste or the like is used as the transfer material, not only will the color tone not match the sealing material, but in the case of a negative type liquid crystal display element, light will pass through the transfer material. There were cases where so-called light leakage occurred, which significantly impaired the appearance. Further, there are black transfer materials such as carbon paste, but since the material is different from that of the sealing material, the colors are different even though they are black, and the appearance is not good.
