Abstract: A display device is capable of realizing low power consumption since a first thin-film transistor having a polycrystalline semiconductor layer and a second thin-film transistor having an oxide semiconductor layer are disposed in an active area. In addition, an opening formed in a bending area is formed to have the same depth as at least one of a plurality of contact holes formed in at least one inorganic insulation layer, which is disposed in the active area, and source and drain electrodes of the second thin-film transistor and source and drain electrodes of the first thin-film transistor, which are disposed below the oxide semiconductor layer, are formed in the same plane using the same material, which simplifies the manufacturing process of the display device.

Abstract: 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.
