Abstract

A display medium includes: a pair of substrates; a spacing member that maintain a gap between the pair of substrates and has a first portion projecting in an intersecting direction, the intersecting direction intersecting a direction in which the pair of substrates face each other; and a holding layer that is provided on at least one of the pair of substrates such that the holding layer fills a space between the at least one of the pair of substrates and an end face of the spacing member, the holding layer covers the first portion from the end face of the spacing member, and the holding layer holds an end part of the spacing member in the direction in which the pair of substrates face each other.

Claims (34)

1. A display medium comprising:

a pair of substrates;

a spacing member that maintains a gap between the pair of substrates and has a first portion projecting in an intersecting direction, the intersecting direction intersecting a direction in which the pair of substrates face each other,

the first portion having a cross-section in the intersecting direction being wider than a cross-section of a region of the spacing member adjoining the first portion; and

a holding layer that is provided on at least one of the pair of substrates such that

the holding layer fills a space between the at least one of the pair of substrates and an end face of the spacing member,

the holding layer covers the first portion from the end face of the spacing member, and

the holding layer holds an end part of the spacing member in the direction in which the pair of substrates face each other.

2. The display medium according to claim 1 , wherein the holding layer has electrical conductivity.

3. The display medium according to claim 1 , further comprising a liquid disposed between the pair of substrates.

4. A method of producing the display medium according to claim 1 , the method comprising:

forming, on a substrate, a coating layer containing a stimulus-curable material that is cured by application of a stimulus;

embedding the first portion of the spacing member into the coating layer; and

applying a stimulus to the coating layer.

5. A display device comprising:

the display medium according to claim 1 , and

a voltage application unit that applies a voltage between the pair of substrates of the display medium.

6. A display medium comprising:

a pair of substrates;

a spacing member that maintains a gap between the pair of substrates, and that, within an entire region spanning from one end to the other end in a direction in which the pair of substrates face each other, and has a first portion that has a cross-sectional area perpendicular to the direction in which the pair of substrates face each other that is larger than that of another portion joined to one of the pair of substrates,

the first portion having a cross-section in the direction in which the pair of substrates face each other being wider than a cross-section of a region of the spacing member adjoining the first portion; and

a holding layer that is provided on at least one of the pair of substrates such that

the holding layer fills a space between the at least one of the pair of substrates and an end face of the spacing member,

the holding layer covers the first portion from the end face of the spacing member, and

the holding layer holds an end part of the spacing member in the direction in which the pair of substrates face each other.

7. The display medium according to claim 6 , wherein the holding layer has electrical conductivity.

8. The display medium according to claim 6 , further comprising a liquid disposed between the pair of substrates.

9. A method of producing the display medium according to claim 6 , the method comprising:

forming, on a substrate, a coating layer containing a stimulus-curable material that is cured by application of a stimulus;

embedding the first portion of the spacing member into the coating layer; and

applying a stimulus to the coating layer.

10. A display device comprising:

the display medium according to claim 6 , and

a voltage application unit that applies a voltage between the pair of substrates of the display medium.
