1. An organic light emitting display device comprising:
a substrate comprising a display area and a peripheral area neighboring each other in a first direction;
a first electrode overlapping the display area;
a second electrode wider than the first electrode in the first direction and overlapping the first electrode;
a light emitting layer disposed between the first electrode and the second electrode;
a first reflective member overlapping both the display area and the peripheral area, comprising a first opening positioned over the display area, comprising a second opening positioned over the peripheral area, and including a metal, an alloy, metal nitride, or conductive metal oxide that has predetermined reflectivity;
a second reflective member at least partially positioned inside the second opening, wherein a reflectivity of the second reflective member is unequal to a reflectivity of the first reflective member; and
an encapsulation layer disposed between the second electrode and the second reflective member and directly contacting each of a face of the first reflective member and a face of the second reflective member,
wherein the face of the first reflective member is coplanar with the face of the second reflective member and is wider than the face of the second reflective member in the first direction, wherein the first reflective member comprises:
a first reflective portion having the first opening and overlapping the display area; and
a second reflective portion having the second opening and overlapping the peripheral area,
wherein the second reflective portion is integrally formed with the first reflective portion,
wherein a reflectivity of the second reflective portion is substantially equal to a reflectivity of the first reflective portion, and wherein the second opening has substantially the same shape and the same size as the first opening.
 
8. An organic light emitting display device comprising:
a substrate comprising a display area and a peripheral area neighboring each other in a first direction;
a first electrode overlapping the display area;
a second electrode wider than the first electrode in the first direction and overlapping the first electrode;
a light emitting layer disposed between the first electrode and the second electrode;
a first reflective member overlapping both the display area and the peripheral area, comprising a first opening positioned over the display area, comprising a second opening positioned over the peripheral area, and including a metal, an alloy, metal nitride, or conductive metal oxide that has predetermined reflectivity;
a second reflective member at least partially positioned inside the second opening, wherein a reflectivity of the second reflective member is unequal to a reflectivity of the first reflective member; and
an insulation layer,
wherein the first reflective member is positioned between the insulation layer and the substrate,
wherein the second reflective member is positioned between the insulation layer and the first reflective member and includes a recess structure positioned inside the second opening, and
wherein the insulation layer includes a first portion overlapping the first opening and a second portion overlapping a portion of the first reflective member positioned over the display area, and wherein the first portion of the insulation layer is narrower than the second portion of the insulation layer, wherein the first reflective member comprises:
a first reflective portion having the first opening and overlapping the display area; and
a second reflective portion having the second opening and overlapping the peripheral area,
wherein the second reflective portion is integrally formed with the first reflective portion,
wherein a reflectivity of the second reflective portion is substantially equal to a reflectivity of the first reflective portion, and wherein the second opening has substantially the same shape and the same size as the first opening.
