<p>PROBLEM TO BE SOLVED: To solve the problems that it is necessary to evaluate characteristics of a TFT corresponding to pixels when poor display resulting from a characteristic abnormality of a thin film transistor occurs in a liquid crystal display device, however, it is necessary to perform probing to a lower electrode in order to evaluate static characteristics of the TFT in an FFS system for applying pixel voltage to the lower electrode, and applying common voltage to an upper electrode, however, the probing is impossible since the upper electrode is arranged so as to cover the lower electrode.SOLUTION: An array substrate comprises: a lower electrode 6; an insulator film which covers the top of the lower electrode; and an upper electrode 8 which is formed on the insulator film, the lower electrode 6 extends on scan wiring of adjacent pixels adjacent to each other so as to stretch over the scan wiring 2, a contact hole 12 is provided on the scan wiring 2, and an analysis pad 60 which has a pad electrode 8a to be formed on the insulator film so as to be connected with the lower electrode 6 is formed so as to cover the contact hole 12.</p> |
