  • Patent number: 9158170
    Abstract: A liquid crystal display (LCD) device, an array substrate in the LCD device, and a method of manufacturing the array substrate are proposed. The LCD device includes an array substrate, a color filter (CF) substrate, and a liquid crystal (LC) layer sandwiched between the array substrate and the CF substrate. A voltage-applying circuit, an auxiliary wire, and a first test pad are disposed on the array substrate. The auxiliary wire is adjacent to the voltage-applying circuit. The auxiliary wire and the voltage-applying circuit are made of the same unit and undergo the same process. If the reference wire is examined to be defective, it could refer that the voltage-applying circuit might have a fault after references and comparisons. So the array substrate could be controlled or repaired, reducing the number of defective products.
