## Abstract

A fiber assembly according to one embodiment of the present disclosure includes a fiber. The fiber includes a core part that contains a coloring compound, a photothermal conversion material, and a color developer/reducer, and a sheath part that covers the core part and has a heat-insulating property.

## Claims

### Claim 1

A display unit comprising:
a first substrate and a second substrate that are disposed to face each other; and
a display body disposed between the first substrate and the second substrate,
the display body including a migrating particle and a fiber assembly in an insulating liquid, the fiber assembly being different in optical reflection property from the migrating particle,
the fiber assembly including a fiber,
the fiber including
a core part that contains a coloring compound, a photothermal conversion material, and a color developer/reducer, and
a sheath part that covers the core part and has a heat-insulating property.

### Claim 2 (depends on 1)

The display unit according to claim 1, wherein the migrating particle includes at least one of an organic pigment, an inorganic pigment, a dye, a carbon material, a metallic material, metallic oxide, glass, and a polymeric material.

### Claim 3

An electronic apparatus comprising a display unit,
the display unit including
a first substrate and a second substrate that are disposed to face each other, and
a display body disposed between the first substrate and the second substrate,
the display body including a migrating particle and a fiber assembly in an insulating liquid, the fiber assembly being different in optical reflection property from the migrating particle,
the fiber assembly including a fiber,
the fiber including
a core part that contains a coloring compound, a photothermal conversion material, and a color developer/reducer, and
a sheath part that covers the core part and has a heat-insulating property.
