を有する液晶パネル及びその製造方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal panel and a method of manufacturing the same, and more particularly, to a liquid crystal panel having an external connection terminal along a side having a liquid crystal injection port and a method of manufacturing the same. About.

をかける方法である。Conventionally, the structure of a liquid crystal panel is such that there is no external connection electrode terminal on the side of the liquid crystal cell on the liquid crystal injection port side as shown in FIG.
Therefore, as shown in FIG.
After the injection port side was brought into contact with a liquid crystal reservoir of about 1 mm, injection was performed by breaking the vacuum. However, in recent years, as the display capacity of the liquid crystal display panel has increased, the panel size has also increased. As a result, for example, in the case of the liquid crystal panel shown in FIG. As the distance approaches, waveform rounding occurs, causing problems such as uneven contrast between left and right of display. In order to solve this problem, the resistance of the transparent electrode has been reduced. However, there is a limit to this, and the method of applying the same driving waveform from the left and right has been recently studied as the best method.

繰り返し使用による液晶溜めの汚染も深刻な問題であり
量産性のある注入方法ではなかった。However, for that purpose, it is necessary to provide a terminal portion also on the injection port side. As a result, for the injection, a method of setting the depth of the liquid crystal reservoir 13 shown in FIG. 8 to, for example, 5 mm or more is necessary. However, this requires a considerable increase in the required amount of liquid crystal, and contamination of the liquid crystal reservoir due to repeated use is a serious problem, and is not a mass-productive injection method.

のない液晶パネルを作製することが可能となった。The upper substrate 1 has segment terminals on the upper and lower sides, and the lower substrate 2 has common terminals on the left and right. In order to manufacture this liquid crystal panel, first, as shown in FIG. 2, the upper and lower substrates were bonded by sealing members 5 and 6, and vacuum injection was directly performed from the substrate end face 11 as shown in FIG. Seal member 5
Since the substrate end face 11 sandwiched between the substrates serves as an injection port as a whole, even if the vacuum is broken immediately after the substrate end face 11 is brought into contact with the liquid crystal reservoir 13, the liquid crystal surrounded by the sealing member 6 is formed. No problems such as air entering the panel occurred. Thereafter, by removing the peripheral portion at the cutting line 8 for the upper substrate and the cutting line 7 for the lower substrate shown in FIG. 3, the sealing member 5 for guiding the liquid crystal is removed, and the external connection terminal portions 9 and 10 are exposed. After letting
The inlet 3 was sealed to form the liquid crystal panel 2. By adopting this method, it is possible to manufacture a liquid crystal panel having an external connection terminal on the injection port side in exactly the same line as a conventional liquid crystal panel having no external connection terminal section on the injection port side. 4. Since the amount of the liquid crystal reservoir shown in FIG. 13 can be made at the same depth as before, it is possible to manufacture a liquid crystal panel having no problem in both mass productivity and quality.
