<p>PROBLEM TO BE SOLVED: To provide an active matrix type liquid crystal display element capable of preventing gate wiring and a counter electrode from corroding due to permeation and invasion of moisture from the outside together with impurities such as salts through a frame shaped sealing material and an end-sealing material for a liquid crystal injection port and maintaining excellent display quality with no inability to write and no generation of light leakage defect for a long period. SOLUTION: A protective film 32 composed of an alkali resistant substance is provided on a surface of an edge part of the gate wiring 31 on the side opposite to a terminal part 31a. Exposure of the edge part of the gate wiring 31 to an alkali generated by an electrochemical reaction between the salt and water caused by a strong electric field generated between the gate wiring 31 and the counter electrode 34, is prevented by the protective film 32 composed of the alkali resistant substance and the corrosion of the gate wiring by the alkali is restrained.</p> |
