表示品質を向上させる傾向にある。Liquid crystal display devices are light-receiving display devices that do not cause eye strain even when viewed for long periods of time, and have low power consumption, making them suitable for use in games, wristwatches, ML consoles, personal computers, etc. Further, applied research for use as a television receiver is underway. Recently, as the display answer ti has increased, the size of the display device itself has increased.
Alternatively, for image display, there is a trend to improve display quality by reducing pixel size.

それによっても同様に断線の発生率が高くなるという問
題点がある。In such a structure, when increasing the size of the display device or reducing the pixel size, the wiring 6.4 in FIG. The probability of wire breakage increases. Also, as pixel sizes become smaller, it is necessary to reduce the line width of wiring.
This also has the problem of increasing the incidence of wire breakage.

部分の表示は、画素ピッチが2倍になった状態となり、
周辺の表示状態とは異和感が残る。This is a method of correcting by inputting the most approximate signal to the regular manual input (IT), but in reality, the part where the approximate signal is input manually will be displayed with twice the pixel pitch,
There remains a sense of incongruity with the surrounding display state.
本発明は上記従来技術の欠点全なくし、表示装置の製造
