Abstract

A display device includes first, second and third connection wiring. The second connection wiring is located in a same layer as the first connection wiring. The third connection wiring is located in a layer different from the first connection wiring. The first connection wiring includes at least one first region running in a first direction and at least one second region running in a second direction different from the first direction. The second connection wiring includes at least one third region running in the first direction and at least one fourth region running in the second direction. The third connection wiring includes at least one fifth region running in the first direction and at least one sixth region running in the second direction. The at least one first region, the at least one third region, and the at least one fifth region are adjacent to one another.
