Abstract
The invention provides a thin film transistor (TFT) substrate comprises a plurality of gate lines, a plurality of data lines, gate terminals, data terminals and thin film transistors as well as a liquid crystal display (LCD) device having the TFT substrate. The gate terminal and/or data terminal contain a first portion and a second portion, and the first potion and the second portion are connected electrically with an end electrode made of a material which is anticorrosive in the air. The thin film transistor substrate of the invention prevents the spreading of the metal corrosion occurred at the gate leads to the display region of the LCD, and therefore the quality of the LCD device can be ensured.
