Abstract
A normal transistor CTFT connected to a data signal line DL and a pixel electrode PX and a spare transistor FTFT in a floating state are formed on a gate line GL. When an operational abnormality occurs in the normal transistor CTFT, the normal transistor CTFT is cut off from the data signal line DL and is cut off from the pixel electrode PX connected via a through hole TH by cutting lines CL. Thereafter, the spare transistor FTFT is connected to the data signal line DL and the pixel electrode PX by repair lines RL.
