The shorting bars(40) surround the active areas to cross with the gate bus lines(31) and data bus lines(35) and make corresponding gate bus lines and data bus lines under equal potential state. Shorting parts(38) are respectively formed in the respective unit pixel for transferring static electricity to the shorting bars when the static electricity is generated.
