Abstract
An electro-luminescence display device for reinforcing its strength is disclosed. In the device, an organic compound layer is provided on a substrate. A packaging plate covers the organic compound layer. Strength reinforcing members are provided at the packaging plate to reinforce strength of the packaging plate.
Claims15
An electro-luminescence display device, comprising:
- an organic compound layer provided on a substrate;
- a packaging plate covering the organic compound layer and a portion of the substrate;
- and
- a strength reinforcing member provided in the packaging plate,
- wherein the strength reinforcing member comprises at least one recessed portion in only a peripheral location of the top surface of the packaging plate so that a bottom surface of only the peripheral location of the plate at the recessed portion is indented toward the substrate at a face of the packaging plate opposed to the substrate to reinforce a strength of the packaging plate, and
- wherein the bottom surface of the strength reinforcing member is indented towards the substrate without extending beyond the organic compound layer.

An electro-luminescence display device, comprising:
- an organic compound layer provided on a substrate;
- a packaging plate covering the organic compound layer;
- and
- a strength reinforcing member provided in the packaging plate,
- wherein the strength reinforcing member comprises first to fourth recessed portions in only peripheral locations of a top surface of the packaging plate so that a bottom surface of only the peripheral locations of the plate at the recessed portions is indented toward the substrate, two of said recessed portions being disposed along an entire minor axis of the packaging plate and the other two recessed portions being disposed along an entire major axis of the packaging plate such that the recessed portions cross each other at corners of the packaging plate.

An electro-luminescence display device, comprising:
- an organic compound layer provided on a substrate;
- a packaging plate covering the organic compound layer;
- a strength reinforcing member provided in the packaging plate;
- and
- a getter provided on an inner surface of the packaging plate at a position above the organic compound layer,
- wherein the strength reinforcing member comprises a recessed portion only in an outer peripheral location in a top surface of the packaging plate so that a bottom surface of the plate at the recessed portion is indented toward the substrate, and
- wherein two of the recessed portions are disposed on a top outer peripheral locations of the packaging plate opposite to one another outside of where the getter is disposed.
4 more elements
An electro-luminescence display device, comprising:
- an organic compound layer provided on a substrate;
- a packaging plate covering the organic compound layer;
- and
- a strength reinforcing member provided in the packaging plate,
- wherein the strength reinforcing member is located only at an outer peripheral portions of the packaging plate and comprises at least one V-shaped recessed portion in a top surface of the packaging plate so that a bottom surface of the plate at the recessed portion is indented toward the substrate at a face of the packaging plate opposed to the substrate.
