LIQUID CRYSTAL DISPLAY PANEL AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To remove an etching stopper layer existing on the crossing section of a gate line and a signal line without increasing the exposure processes and to decrease the number of processes, especially the number of exposure processes by forming one or plural openings on the crossing section. SOLUTION: A gate electrode 4 and a gate line 5 integrally connected to the gate electrode 4 are formed on a light-transmitting substrate 2. Two rectangular slit-like openings 5b are formed at the section 5a (crossing section) where the gate line 5 crosses a signal line through an insulating layer. When an etching stopper 12 in the almost same form as a photoresist, namely in the almost same form as the gate electrode 4 and gate line 5, is to be formed by wet etching, the etching stopper layer 12 is removed from the crossing section 5a where the openings 5b are formed by the side-etching effect that the etching stopper 12 is etched in the width direction.
