Because it is supported through, even if it is applied to the liquid crystal display device from outside by vibration, shock, or the like,
Since there is no strong impact, there is no disconnection of the conductive pattern.

Since a flexible substrate on which a thin conductive pattern of about 18 to 50 μm is formed is also deployed and arranged in a plane, no stress acts on the conductive pattern, and even if the liquid crystal display device is subjected to external vibration or shock. Since it is transmitted while being buffered, no large stress acts on the conductive pattern. Therefore, a disconnection accident or the like of the conductive pattern does not occur.
