Abstract

White particles for display including at least one of a chain or cyclic polysilane compound having a polysilane structure represented by the following Formula (I) or a halogen-substituted compound thereof: wherein in Formula (I), A represents a phenyl group, B represents an alkyl group or a phenyl group, and n represents an integer of from 5 to 1000.

Claims (20)

1. A display medium comprising:

a pair of substrates facing each other with a space therebetween, at least one of the substrates being transparent;

color particles that are located between the substrates and move between the substrates in response to an electric field formed between the substrates;

white particles for display that are located between the substrates; and

a dispersing medium that is located between the substrates and disperses the color particles and the white particles for display,

the white particles for display comprising at least one of a chain or cyclic polysilane compound having a polysilane structure represented by the following Formula (I) or a halogen-substituted compound thereof:

wherein in Formula (I), A represents a phenyl group, B represents an alkyl group or a phenyl group, and n represents an integer of from 5 to 1000.

2. The display medium according to claim 1 , wherein the polysilane compound comprises a chain polysilane compound having a structure represented by the following Formula (I-1A):

wherein in Formula (I-1A), n represents an integer of from 5 to 1000.

3. The display medium according to claim 1 , wherein the polysilane compound comprises a cyclic polysilane compound having a structure represented by the following Formula (I-2A):

4. A display medium comprising:

a pair of electrodes;

white particles for display that are located between the electrodes and move between the electrodes in response to an electric field formed between the electrodes; and

a dispersing medium that is located between the electrodes and disperses the white particles for display, the white particles for display comprising at least one of a chain or cyclic polysilane compound having a polysilane structure represented by the following Formula (I) or a halogen-substituted compound thereof:

wherein in Formula (I), A represents a phenyl group, B represents an alkyl group or a phenyl group, and n represents an integer of from 5 to 1000.

5. The display medium according to claim 4 , wherein the polysilane compound comprises a chain polysilane compound having a structure represented by the following Formula (I-1A):

wherein in Formula (I-1A), n represents an integer of from 5 to 1000.

6. The display medium according to claim 4 , wherein the polysilane compound comprises a cyclic polysilane compound having a structure represented by the following Formula (I-2A):

7. A display device comprising the display medium according to claim 1 and an electric field formation unit that forms an electric field between the pair of substrates.

8. A display device comprising the display medium according to claim 4 and an electric field formation unit that forms an electric field between the pair of electrodes.
