Title:
THIN FILM TRANSISTOR AND LIQUID CRYSTAL DISPLAY USING THE SAME
Document Type and Number:
Japanese Patent JP3878705
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a TFT wherein a gate electrode, a source electrode and a drain electrode are formed with the same layer, and to obtain a liquid crystal display using the TFT as a guard resistance preventing conduction between the gate electrode and the source or drain electrode.
SOLUTION: A floating gate electrode 4 is formed on a glass substrate 3, and a gate protective film 5 is formed on the floating gate electrode 4, moreover a semiconductor i layer 6 is formed on the gate protective film 5, and a semiconductor n layer 7 is formed on the semiconductor i layer 6, and a source and drain electrode 8 is formed on the semiconductor n layer 7, moreover a gate electrode 9 is formed on the gate protective film 5 on which the semiconductor i layer 6 is not formed.
