THIN FILM TRANSISTOR SUBSTRATE AND DISPLAY DEVICE HAVING THE SAME

摘要

PURPOSE: A TFT(Thin Film Transistor) in which a test process facilitates and a display device including the same are provided to easily perform a test process according to a structure of a shorting bar and a connection wire. CONSTITUTION: A first signal wiring is extended toward a first direction. A signal line pad is formed in one end of the first signal wiring. Shorting bars(50a, 50b) are formed in the other end of the signal wiring in order to decentralize the static electricity of the signal wiring and extended toward the first direction. A connection wiring(60) electrically connects the signal wiring and shorting bar. The first signal wiring comprises the even numbered turn and the odd numbered signal wiring and is electrically connected to the shorting bar'.
