Abstract
Improved thin film transistors resistant to static electricity induced line faults are provided. The thin film transistors formed in accordance with the invention are particularly well suited for use in an active matrix substrate for a liquid crystal display panel. The liquid crystal display panels include an additional layer formed between crossing source lines and gate lines to provide a higher breakdown voltage between the source lines and gate lines than at the gate insulating layer of the thin film transistors or at a display capacitor.
