Abstract
An electroluminescence (EL) device is resistant to external shock and has a prolonged service life. In the device, an emissive element substrate has a first electrodes formed on a substrate, an emissive element layer formed over the first electrodes, and a second electrode formed on the emissive layer. A sealing member covers the second electrode of the emissive element substrate. Shock buffers in pillar, spherical, or sheet form are arranged in a gap between the second electrode and the sealing member. When the shock members are made of a hard material, they are preferably arranged above the non-emissive areas in the EL device.
Claims31
An electroluminescence device with a shock buffering function, comprising:
- an emissive element substrate comprising a first electrode formed on a substrate and a second electrode formed above both said first electrode and an intervening emissive layer;
- a sealing member for sealing an element forming surface of said emissive element substrate;
- and
- shock buffers arranged in a gap between said emissive element substrate and said sealing member.
An electroluminescence device with shock buffer function, comprising:
- an emissive element substrate having a first electrode formed on a substrate and a second electrode formed above both said first electrode and an intervening emissive layer;
- a sealing member for sealing an element forming surface of said emissive element substrate;
- a sheet-like shock buffer arranged in a gap between said emissive element substrate and said sealing member, and
- a desiccant disposed in a gap between said sealing member and the shock buffer.
A sealing member, which covers an element forming surface of an emissive element substrate, said emissive element substrate having a first electrode formed on a substrate and a second electrode formed above both said first electrode and an intervening emissive layer;
- said sealing member comprising:
- one or more shock buffers protruding from or securely fixed in the surface of said sealing member which faces said emissive element substrate.
