Abstract
A liquid crystal display device includes a display circuit having data lines and scanning lines arranged in two-dimensional matrix, and switching elements connected between the data lines and the scanning lines. A first inspection circuit is also provided, including an inspection voltage input and/or output terminal for inputting and/or outputting an inspection voltage to/from one ends of the data lines via a first analog switch. A second inspection circuit includes an inspection voltage input and/or output terminal for inputting and/or outputting an inspection voltage to/from the other ends of the data lines. The display circuit, the first inspection circuit, and the second inspection circuit are provided on one substrate, and the first inspection circuit is constructed to be separated from the rest of the display circuit.
