Stage: PROBLEM TO BE SOLVED: To provide a display device having low power consumption and high productivity.SOLUTION: An organic light-emitting display device comprises a first thin-film transistor 150 that is applied as a switching device for a sub pixel and that includes a polycrystalline semiconductor layer 154 in an active region, and a second thin-film transistor 100 that is applied as a drive transistor for the sub-pixel and that includes an oxide semiconductor layer 104, and therefore lower power consumption is achieved. An opening 192 that is provided in a bending region BA and one of contact holes 110S, 110D that are provided in the active region have the same depth d1, and thus the opening and the contact holes are formed in the same step to simplify the manufacturing process. A second source electrode 106 of the second thin-film transistor overlaps with a second gate electrode 102 of the second thin-film transistor with an upper interlayer insulator film 124 therebetween to form a first storage capacitor Cst.SELECTED DRAWING: Figure 7 (Grant)
