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.
