Abstract
An organic light-emitting display device including an encapsulating layer and an encapsulating substrate disposed on the encapsulating layer is provided. The encapsulating layer may cover a light-emitting element. The encapsulating substrate may include a material having high thermal conductivity. A reinforcing member may overlap the light-emitting element between the encapsulating layer and the encapsulating substrate. Thus, in the organic light-emitting display device, the rigidity of the encapsulating substrate may be complemented by the reinforcing member. Thereby, the organic light-emitting display device may prevent damage of the light-emitting element due to external impact.
Claims22

- a plurality of metal beads within the bead holding encapsulation layer;
- and
- an encapsulating substrate overlying the bead holding encapsulation layer.
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.
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;
- a first 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;
- and
- 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.
