Abstract
A display apparatus includes: an electrode layer; a display layer that is provided on the electrode layer, and that includes a plurality of containers containing at least one of positively charged first particles and negatively charged second particles; a film provided on the display layer; and a movable electrode portion capable of applying voltage to part of a region of the display layer through the film, the film being a conductive film having lower conductivity in a planar direction than in a thickness direction of the film.
Claims15
A display apparatus comprising:
- an electrode layer being applied a voltage by a voltage applying section;
- a display layer that is provided above the electrode layer, and that includes a plurality of containers, each of the plurality of containers containing at least one of positively charged first particles and negatively charged second particles;
- a film provided above the display layer;
- and
- a movable electrode portion capable of applying voltage to part of a region of the display layer through the film,
- the film being a conductive film having lower conductivity in a planar direction of the film than in a thickness direction of the film,
- the movable electrode being applied a voltage by a voltage applying section that passes through the film to the electrode layer, and
- the film including a plurality of conductive portions and an insulating portion, an area of the plurality of conductive portions being larger than an area of the insulating portion at a display region.

A display sheet comprising:
- a display layer including a plurality of containers containing at least one of positively charged first particles and negatively charged second particles;
- and
- a film provided on the display layer, wherein the film includes:
- a plurality of conductive portions that receives an applied voltage from a movable electrode portion, and
- an insulating portion that is provided between the plurality of conductive portions, the insulating portion being configured to insulate the plurality of conductive portions from each other, and an area of the plurality of conductive portions being larger than an area of the insulating portion at a display region,
- wherein the film passes through the applied voltage from a first surface of the film to a second surface of the film opposite the first surface.
