It becomes. The opposing surface ζ of the upper electrode substrate 1 has a transparent conductive film (IT
The necessary electrodes 5 and 7 are formed by forming a transparent conductive film and performing etching.

治工具類を必要とする。In the structure shown in Fig. 2, the terminals 6 are simply arranged in one row, and if the number of terminals becomes very large, the terminal pitch P will be approximately equal to the number of terminals ζ due to restrictions on external dimensions due to product manufacturing. This becomes proportionally narrower, making it difficult to connect the external connection substrate on which the drive circuit is mounted and the liquid crystal display element. For example, P ” 0.5
In the case of mm, the width of the terminal 6 is usually about 0.25 mm, but in order to ensure a secure connection, it is necessary to increase the assembly accuracy within ±0.1 to ±0.2 mm, which requires very precise requires appropriate jigs and tools.
