Abstract
An object of the present invention is to realize a display device having a layered wiring structure, that is capable of detecting leakage without fail by using a simple testing circuit.Source bus lines (SL) are wired such that, in the layered region, two source bus lines (SL) adjacent in a vertical direction are a combination of a source bus line (SL) of an odd-numbered column and a source bus line (SL) of an even-numbered column, and two source bus lines (SL) adjacent in a horizontal direction are a combination of a source bus line (SL) of an odd-numbered column and a source bus line (SL) of an even-numbered column. Potentials of different magnitudes are supplied respectively to source bus lines (SL) of odd-numbered columns and source bus lines (SL) of even-numbered columns via testing lines.
