1. A display device comprising:
a reinforced substrate having a flexible region and a reinforced region adjacent to the flexible region;
a display layer disposed on the reinforced substrate and including a thin-film transistor, an organic light emitting display and a thin-film encapsulating layer, wherein the thin-film encapsulating layer is disposed on the organic light emitting display; and
a first barrier layer configured to block moisture or oxygen toward the display layer and disposed between the reinforced substrate and the display layer,
wherein the reinforced substrate comprises:
a first reinforced layer comprising a reinforced portion disposed in the reinforced region and a plurality of patterns disposed in the flexible region, each of the plurality of patterns being disconnected from one another by respective ones of a plurality of patterned spaces and disconnected from the reinforced portion; and
a first substrate that is disposed on the first reinforced layer and has flexibility,
wherein a modulus of elasticity of the first reinforced layer is greater than a modulus of elasticity of the first substrate,
wherein the first substrate surrounds at least three surfaces of the reinforced portion of the first reinforced layer,
wherein the organic light emitting display includes a pixel electrode including a reflective electrode, an intermediate layer disposed on the pixel electrode, and a counter electrode disposed on the intermediate layer,
wherein the organic light emitting display emits light in a direction opposite from the reinforced substrate, and
wherein the light emitted from the organic light emitting display is emitted to outside of the display device through the thin-film encapsulating layer.
