Abstract: A display device includes a first active pattern disposed on a substrate and including a first material, a second active pattern including a second material that is different from the first material of the first active pattern, a voltage line disposed under the second active pattern, a horizontal transmission line disposed on the second active pattern, and extending in a first direction and a connection pattern spaced apart from the horizontal transmission line, disposed on a same layer as the horizontal transmission line, and making electrical contact with the second active pattern and the voltage line. The horizontal transmission line and the voltage line may be spaced apart from each other and the second active pattern and the voltage line may make contact with each other through the connection pattern. Accordingly, a contact resistance value may be reduced, and a distribution of contact resistance values may resultantly be reduced.
