Abstract

A member for an electroluminescent device permitting a production cost reduction and an electroluminescent device containing the same. The member for an electroluminescent device contains a removing agent for removing a predetermined gas component and an adhesion member fixed to the removing agent.

Claims

1. A member for an electroluminescent device, comprising:

a removing agent for removing a predetermined gas component;

an adhesion member fixed to the removing agent wherein the adhesion member is a three-layer laminate comprising a substrate layer sandwiched between two adhesive layers; and

a sheet member having a gas permeable portion covering said removing agent.

2. The member for an electroluminescent device as claimed in claim 1, wherein said gas permeable portion is composed of a porous material of polytetrafluoroethylene.

3. The member for an electroluminescent device as claimed in claim 1, wherein said gas permeable portion is composed of a porous material of a polymer having a crystal structure.

4. The member for an electroluminescent device as claimed in claim 1, wherein said gas permeable portion is composed of a porous material of a thermoplastic resin.

5. The member for an electroluminescent device as claimed in claim 4, wherein said thermoplastic resin is a polyolefin resin.

6. The member for an electroluminescent device as claimed in claim 1, wherein said adhesion member has a modulus of elasticity within the range of from 1×

10³ to 1×

10¹⁰ Pa at 25°

C.

7. The member for an electroluminescent device as claimed in claim 1, wherein said member for an electroluminescent device has a modulus of elasticity within the range of from 1 MPa to 1×

10⁶ MPa at 25°

C.

8. The member for an electroluminescent device as claimed in claim 1, wherein the thickness of said member for an electroluminescent device is 5 mm or less.

9. An electroluminescent device containing a member for an electroluminescent device comprising a removing agent for removing a predetermined gas component, an adhesion member fixed to the removing agent wherein the adhesion member is a three-layer laminate comprising a substrate layer sandwiched between two adhesive layers, and a sheet member having a gas permeable portion covering said removing agent.
