Organic light-emitting display device having an encapsulating substrate of high thermal conductivity

An organic light-emitting display device comprising:

• a device substrate including a display area and a non-display area;
• a light-emitting element on the display area of the substrate;
• an encapsulation layer overlying the light-emitting element, the encapsulation layer being in the display area;
• a plurality of moisture absorbing beads positioned within the encapsulation layer;
• a bead holding encapsulation layer overlying a portion of the encapsulation layer, the bead holding encapsulation layer overlapping with the display area of the substrate;
• an encapsulating substrate overlying the bead holding encapsulation layer and the encapsulation layer;
• and
• metal beads within the bead holding encapsulation layer,
• wherein the metal beads within the bead holding encapsulation layer are comprised of a ferrous metal.

An organic light-emitting display device comprising:

• a device substrate including a display area and a non-display area disposed outside the display area;
• a light-emitting element on the display area of the device substrate;
• an encapsulating layer on the light-emitting element, the encapsulating layer being in the display area and also in the non-display area of the device substrate;
• an encapsulating substrate on the encapsulating layer;
• a first reinforcing member between the encapsulating layer and the encapsulating substrate, the first reinforcing member overlapping with the display area of the device substrate;
• and
• first metal beads within the first reinforcing member,
• wherein the first metal beads within the first reinforcing member are comprised of a ferrous metal.

An organic light-emitting display device comprising:

• an encapsulating substrate on a device substrate;
• a light-emitting element on an upper surface of the device substrate facing the encapsulating substrate;
• a reinforcing member on a lower surface of the encapsulating substrate facing the device substrate;
• an encapsulating layer between the device substrate and the encapsulating substrate, the encapsulating layer surrounding the light-emitting element and the reinforcing member, and
• a plurality of metal beads within the reinforcing member,
• wherein the metal beads within the reinforcing member are comprised of a ferrous metal.
