1. A flexible electroluminescent display apparatus, comprising:
a flexible substrate including an active area and a bending area extending from the active area;
a transistor disposed in the active area of the flexible substrate;
a light emitting element disposed in the active area of the flexible substrate, the light emitting element being electrically connected to the transistor;
a first wiring line and a second wiring line disposed in the bending area of the flexible substrate;
a first planarization layer disposed on the first wiring line; and
a second planarization layer disposed on the second wiring line,
wherein the second wiring line is disposed on the first planarization layer,
wherein the first wiring line and the second wiring line are directly connected to each other to receive a same signal,
wherein the first planarization layer extends continuously from a first side of the bending area to a second side of the bending area opposite to the first side, the first side of the bending area being adjacent to the active area,
wherein the first wiring line and the second wiring line remain spaced apart from each other in the bending area by the first planarization layer, and
wherein both of the first planarization and the second planarization layer are disposed between the light emitting element and the transistor in the active area, the second wiring line is disposed between the first planarization layer and the second planarization layer in the bending area, and the second planarization layer extends continuously from the first side of the bending area to the second side of the bending area.
