Electrophoretic display device and electronic apparatus
View Patent ↗An electrophoretic display device includes a first substrate on which a pixel electrode and another pixel electrode that is adjacent to the pixel electrode are formed, a second substrate on which a common electrode facing the pixel electrode and the another pixel electrode that is adjacent to the pixel electrode is formed, a plurality of electrophoretic elements that is sandwiched by the first substrate and the second substrate and has charged electrophoretic particles, and an adhesive agent layer that is disposed between the plurality of electrophoretic elements and the first substrate. A floating electrode that is electrically isolated is disposed between the pixel electrode and the another pixel electrode that is adjacent to the pixel electrode on the first substrate.
1. An electrophoretic display device comprising:
a first substrate,
a pixel electrode being disposed on the first substrate,
another pixel electrode that is adjacent to the pixel electrode being disposed on the first substrate;
a second substrate,
a common electrode being disposed on the second substrate, the common electrode facing the pixel electrode and the another pixel electrode;
electrophoretic elements disposed between the first substrate and the second substrate, the electrophoretic elements having charged electrophoretic particles;
an adhesive agent layer disposed between the electrophoretic elements and the first substrate; and
a floating electrode disposed on the first substrate in the same layer as the pixel electrode and the another pixel electrode, the floating electrode being located between the pixel electrode and the another pixel electrode in plan view, the floating electrode being electrically isolated from the pixel electrode and the another pixel electrode.
2. The electrophoretic display device according to claim 1 , wherein the floating electrode is disposed along one side of the pixel electrode and extends along an extended line of the one side.
3. The electrophoretic display device according to claim 1 , wherein the floating electrode is disposed to extend to a floating electrode that is disposed along one side of the another pixel electrode, which is adjacent to the pixel electrode, on the extended line of the one side.
4. The electrophoretic display device according to claim 1 , wherein the floating electrode is disposed so as to enclose the periphery of the pixel electrode.
5. The electrophoretic display device according to claim 1 , wherein the pixel electrode and the floating electrode are formed of a same material.
6. The electrophoretic display device according to claim 1 , wherein an insulation layer that is formed of a material having electrical resistance higher than that of the adhesive agent layer is disposed between the pixel electrode and the floating electrode that is adjacent to the pixel electrode.
7. The electrophoretic display device according to claim 6 , wherein the insulation layer is disposed so as to cover the floating electrode and protrudes to the electrophoretic elements side relative to an upper face of the pixel electrode.
8. An electronic apparatus comprising the electrophoretic display device according to claim 1 .
