ACTIVE MATRIX SUBSTRATE AND METHOD FOR TESTING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an active matrix substrate capable of preventing a destroy of an insulation film even after testing; and a method for testing the substrate. SOLUTION: A short-circuit member 11 between a gate line block 13 and a source line block 14 has in parallel a first portion 111 which is in from a short-circuit state to an insulation state by laser irradiation in between both blocks; and a second portion 112 which is in from an insulation portion to a short-circuit portion by laser irradiation.
