Display device
View Patent ↗Even when gate lines are pulled around at both left and right picture frame regions, it is possible to prevent a gate wiring pattern which is constituted of the gate lines and gate-line pull-around lines and a storage wiring pattern which is constituted of storage lines and a common line which connects storage lines each other from getting over each other. The gate lines GL 1 , GL 2 are pulled around by the gate-line pull-around lines GLL 1 , GLL 2 in both left and right picture frame regions. The common lines B 2 , B 3 which connect the storage lines STL each other are formed at both left and right picture frame regions. Further, the gate wiring pattern which is constituted of the gate lines GL 1 , GL 2 and the gate-line pull-around lines GLL 1 , GLL 2 and the storage wiring pattern which is constituted of the storage lines STL and the common lines B 2 , B 3 do not cross each other.
