Patent ID: 7528903

Claim:
A display device comprising: a first substrate; a second substrate; and microcapsules sandwiched between the first substrate and the second substrate, the microcapsules constituting a display area, the microcapsules encapsulating a display material whose optical properties change in response to electrical stimulation, wherein a conductive material for conducting between the substrates is provided between the first substrate and the second substrate to constitute a vertically conducting portion; and wherein the thickness of the conductive material is set such that the distance between the first substrate and the second substrate at the vertically conducting portion is larger than the distance between the first substrate and the second substrate in the display area; and the thickness of the conductive material is set such that the distance between the first substrate and the second substrate at the vertically conducting portion is larger than the distance between the first substrate and the second substrate in the display area by a range of 10 to 200 μm.
