Image display medium

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

1. An image display medium comprising: 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; andan insulating layer fixed to the at least one of the first substrate and the second substrate by the first bonding layer,whereinthe first bonding layer has a Young's modulus smaller than the substrate formed with the insulating layer and the insulating layer.

2. The image display medium as claimed in claim 1, which comprises: a first electrode formed on inner surface of the first substrate;a second electrode formed on inner surface of the second substrate;a partition member partitioning a gap between the first substrate and the second substrate; andparticles filled into the gap partitioned by the partition members.

3. The image display medium as claimed in claim 2, which comprises: a coat layer formed inside the at least one of the first substrate and the second substrate, and covering at least one of the first electrode and the second electrodes.

4. The image display medium as claimed in claim 2, which comprises: a second bonding layer bonding the partition member to one of the first substrate and the second substrate,whereinthe partition members are directly bonded to the other substrate.

5. The image display medium as claimed in claim 2, which comprises: an insulating film, whereinthe insulating layer is formed inside one of the first substrate and the second substrate,the partition members are formed on the other substrate opposite to the one substrate formed with the insulating layer, andthe insulating film covers the partition member and the one substrate formed with the partition member.

6. The image display medium as claimed in claim 5, wherein the partition member is fixed to the insulating layer by the second bonding layer.
