Patent abstract
An inspection circuit is constructed by first inspection TFTs provided to one end sides of signal lines, and second inspection TFTs provided to the other end sides of the signal lines. By using both the first inspection TFTs and the second inspection TFTs, the driving capability can be secured while miniaturizing the first inspection TFTs and the second inspection TFTs. Therefore, the signal lines can be reliably inspected while saving the space for the inspection circuit.
