the array substrate further comprises a third wiring which is perpendicular to the first wiring,
the second belt portion further overlaps the third wiring,
the third wiring includes a second projection portion,
at least a part of the second projection portion is located with a displacement from the first belt portion, and is opposed to the first wiring,
the first projection portion is protruded from a first edge of the first belt portion to an outside of the first belt portion, and
the second projection portion is protruded from a second edge of the first belt portion to the outside of the first belt portion.
3. The liquid crystal display panel of claim 1 , wherein
the first wiring further includes a second projection portion,

a liquid crystal layer held between the array substrate and the counter-substrate; and
a spacer disposed between the array substrate and the counter-substrate,
wherein
at least a part of the spacer is opposed to an intersection part between the first belt portion and the second belt portion,
at least a part of the first projection portion is located with a displacement from the first belt portion, and is opposed to the second wiring,
the first wiring is a signal line, and
the second wiring is either one of a gate line and a storage capacitance line.
7. The liquid crystal display panel of claim 6 , wherein
the array substrate further comprises a third wiring which is perpendicular to the first wiring,
