A touch sensor integrated type display device capable of reducing its thickness and simplifying its manufacturing process. The display device includes first electrodes, second electrodes, first connecting wires, and second connecting wires. The first electrodes are arranged on a substrate in parallel in a first direction, and the second electrodes are arranged in parallel in the first direction and a second direction crossing the first direction without contacting the first electrodes. Each first connecting wire is connected with at least one the first electrodes. Each second connecting wire connects the second electrodes to each other in the second direction. A touch driving voltage is supplied to the first connecting wires and a common voltage is supplied to the second connecting wires so that mutual capacitance is generated between the first electrodes and the second electrodes.
