1. A flexible display device, comprising:
a base layer including an active area having a plurality of pixels and a non-active area surrounding the active area and including a bending area;
at least one transistor disposed on the base layer in the active area and including an activation pattern, a control electrode, an input electrode and an output electrode;
a via layer covering the at least one transistor;
a light emitting element disposed on the via layer in the active area and electrically connected with the transistor, the light emitting element including an anode electrode, an emission layer and a cathode electrode;
a pixel definition layer disposed on the via layer and exposing at least a part of the anode electrode;
an encapsulation layer disposed on the light emitting element layer;
first data pads disposed in the non-active area adjacent to the active area and electrically connected with the plurality of pixels;
third data pads disposed in the non-active area in a direction away from the first data pads and the active area;
second data pads disposed between the first data pads and the third data pads;
connection lines connecting the second data pads and the third data pads;
an insulating layer covering a part of each of the first data pads, the second data pads and the third data pads and covering the connection lines;
a drive circuit disposed to overlap the first data pads and the second data pads;
a printed circuit board electrically connected with the third data pads and configured to transmit image data corresponding to the image to the pixels;
input bumps connected with the drive circuit and configured to receive the image data; and
output bumps connected with the drive circuit and configured to output the image data to the pixels,
wherein the bending area is disposed between the active area and the first data pads and is disposed between the active area and the drive circuit, and
wherein the insulating layer is a same layer as the via layer.
