Abstract

An image display medium includes: a first substrate; a second substrate facing the first substrate; a first bonding layer provided inside at least one of the first substrate and the second substrate; and an insulating layer fixed to the at least one of the first substrate and the second substrate by the first bonding layer, wherein the first bonding layer has a Young's modulus smaller than the substrate formed with the insulating layer and the insulating layer.

Claims (42)

1. An image display medium comprising:

a first substrate;

a second substrate facing the first substrate;

a first bonding layer provided inside the first substrate;

a first electrode having sides formed on an inner surface of the first substrate;

a second electrode formed on an inner surface of the second substrate;

an insulating layer fixed to the first substrate by the first bonding layer; and

a coat layer formed inside the first substrate, and covering the first electrode including the sides of the first electrode,

wherein

the first bonding layer has a Young's modulus smaller than the first substrate and the insulating layer, and is provided between the first substrate and the insulating layer.

2. The image display medium as claimed in claim 1 , which comprises:

a partition member partitioning a gap between the first substrate and the second substrate; and

particles filled into the gap partitioned by the partition member.

3. The image display medium as claimed in claim 2 , which comprises:

a second bonding layer bonding the partition member to the first substrate,

wherein

the partition member is bonded to the second substrate.

4. The image display medium as claimed in claim 2 , further comprising:

an insulating film,

wherein

the insulating film is formed inside the second substrate,

the partition member is formed on the second substrate, and

the insulating film covers the partition member and the second substrate.

5. The image display medium as claimed in claim 3 , wherein at least one of the partition members is fixed to the insulating layer by the second bonding layer.

6. The image display medium as claimed in claim 1 , wherein the first bonding layer has a Young's modulus of 5000 kg/cm2 or less.

7. The image display medium as claimed in claim 1 , wherein the first bonding layer has light transmittance of 90% or more, and saturation of 1 or less.

8. The image display medium as claimed in claim 1 , wherein the insulating layer has a thickness of 300 nm or more, and 30 mm or less.

9. The image display medium as claimed in claim 1 , wherein the insulating layer has a light transmittance of 90% or more, and a saturation of 1 or less.

10. The image display medium as claimed in claim 3 , wherein the second bonding layer has a Young's modulus smaller than the insulating layer bonded by the second bonding layer.

11. The image display medium as claimed in claim 3 , wherein the second bonding layer has an elasticity modulus of 5000 kg/cm2 or less.

12. An image display medium comprising:

a first substrate;

a second substrate facing the first substrate;

a first bonding layer provided inside the first substrate;

a first electrode having sides formed on inner surface of the first substrate;

a second electrode formed on inner surface of the second substrate;

an insulating layer fixed to the first substrate by the first bonding layer;

a coat layer formed inside the first substrate, and covering the first electrode including the sides of the first electrode; and

a partition member partitioning a gap between the first substrate and the second substrate, the partition member being covered in an insulating film,

wherein

the first bonding layer has a Young's modulus smaller than the first substrate and the insulating layer, and is provided between the first substrate and the insulating layer, and

the partition member is fixed to the insulating layer by the second bonding layer.
