Abstract
In one embodiment, an array substrate includes an active area in the shape of a rectangle, and first, second third and fourth end portions, surrounding the active area. A source control circuit is electrically connected with one end of the source lines drawn to the third end portion from the active area. First and second common terminals of a common potential are formed in the first end portion. A power supply line is electrically connected with the first common terminal and extends along the second, third and fourth end portions in this order, and connected with the second common terminal. A branch wiring is electrically connected with an intermediate portion of the electric power supply line and the source control circuit, and extending in the first direction.
