1. An organic light emitting diode (OLED) display comprising:
a substrate;
an organic light emitting diode disposed on the substrate;
a first layer disposed on the substrate, contacting the organic light emitting diode, and comprising metal oxide;
a second layer disposed on the first layer and comprising an inorganic material; wherein at least one surface of the second layer directly contacts the first layer at least in an area corresponding to the organic light emitting diode;
a third layer disposed on the second layer and comprising an organic material; and
a fourth layer disposed on the third layer, comprising an inorganic material, and directly contacting the second layer; wherein each of the second layer and the fourth layer comprises a region extending to an outer side of the organic light emitting diode along the substrate, and wherein the second layer is in direct contact with the fourth layer and overlaps the fourth layer at the region extending to at the outer side of the organic light emitting diode along the substrate.
