Title:
ARRAY SUBSTRATE FOR LIQUID CRYSTAL DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP3672302
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a test wire from being broken during dry etching and to prevent a test error by shortening a process time by forming source and drain electrodes of molybdenum and forming the test wire of a gate substance.
SOLUTION: When a short bar which is formed on the outer shell of a substrate and can connect an odd-numbered gate wire and an even-numbered data wire and a test pad applying a signal for inspection to the short bar are connected through a connecting wire in a 4-mask process using molybdenum as substances forming the source and drain electrodes, the formation of the connection part of molybdenum can be avoided by forming each test pad and the connecting wire of the gate substance and indirectly connecting the connection part to the short bar formed of molybdenum (Mo) by using a different transparent electrode pattern, so the defect that the connecting wire formed on the outer shell of the substrate is etched can be prevented during a process of patterning the source electrode and drain electrode.
