Disclosed is a display device that is capable of being driven with low power consumption. A first thin-film transistor including a polycrystalline semiconductor layer and a second thin-film transistor including an oxide semiconductor layer are disposed in an active area, thereby reducing power consumption. At least one opening formed in a bending area is formed to have the same depth as any one of contact holes formed in the active area, thereby making it possible to form the opening and the contact holes through the same process and consequently simplifying the process of manufacturing the device. Since a high potential supply line and a low potential supply line overlap each other with a protective film formed of an inorganic insulation material interposed therebetween, short-circuiting of the high potential supply line and the low potential supply line may be prevented.
