1. An organic light emitting diode display device, comprising:
a substrate having an emitting area and a non-emitting area;
an insulating layer over the substrate, the insulating layer having micro lenses including a plurality of convex portions in the emitting area;
a first electrode over the insulating layer;
a bank over the first electrode in the non-emitting area;
an emitting layer over the first electrode extending to a top surface of the bank in non-emitting area; and
a second electrode over the emitting layer,
wherein a portion of the plurality of convex portions extends from the emitting area to the non-emitting area,
wherein the first electrode extends to a slanting surface of the plurality of convex portions in the non-emitting area,
wherein a thickness of the insulating layer in the non-emitting area is greater than a thickness of the plurality of convex portions of the micro lens of the insulating layer in the emitting area,
wherein the bank covers the first electrode over the slanting surface of the convex portion of the insulating layer in the non-emitting area,
wherein the insulating layer further includes at least one wall in the emitting area, and
wherein the at least one wall extends from a top surface of the insulating layer, and a top surface of the at least one wall is exposed through the first electrode.
