Abstract
A liquid crystal display panel includes a gate line and a signal line intersecting the gate line at an intersection portion where the gate line and the signal line intersect each other. The gate line includes at least two conductive portions and at least one opening portion on the intersection portion. The at least one opening portion on the gate line is used for removing an etching stopper layer.
Claims22
A liquid crystal display panel, comprising:
- a gate line;
- a signal line intersecting said gate line at an intersection portion;
- and
- an etching stopper layer formed on said gate line except at said intersection portion,
- wherein said gate line comprises at least two conductive portions and at least one opening portion directly on said intersection portion where the gate line and the signal line intersect each other.
