Abstract

A sturdy electronic device is provided. A reliable electronic device is provided. A novel electronic device is provided. An electronic device includes a first board, a second board, a display portion having flexibility, and a power storage device having flexibility. The first board and the second board face each other. The display portion and the power storage device are provided between the first board and the second board. The display portion includes a first surface facing the power storage device. The first surface includes a first region not fixed to the power storage device. The first region overlaps with a display region of the display portion.

First claim

What is claimed is:

1. An electronic device comprising:
a first board;
a second board facing the first board;
a display portion between the first board and the second board;
a circuit board between the first board and the second board; and
a power storage device comprising:
an exterior body comprising a laminate film; and
an electrolyte comprising lithium ions,

wherein the display portion comprises a third board, a display element and a circuit portion,
wherein the second board comprises a first region, a second region and a third region,
wherein the third board comprises a fourth region and a fifth region,
wherein the first region and the fourth region are fixed to each other,
wherein the second region and the fifth region are not fixed to each other,
wherein the third region and the power storage device are fixed to each other,
wherein the circuit board is electrically connected to the power storage device and the circuit portion, and
wherein the display portion is positioned on an opposite side of the second board from the power storage device.

2. The electronic device according to claim 1 , wherein a distance between the second region and the fifth region changes when a shape of the electronic device changes.

3. The electronic device according to claim 1 , wherein the display portion is provided on the first board with an adhesive layer therebetween.

4. The electronic device according to claim 1 , wherein a distance between the first board and the second board changes when a shape of the electronic device changes.

5. The electronic device according to claim 1 , wherein the electronic device is configured to be worn such that the second board is in contact with a user's arm.

6. The electronic device according to claim 1 , further comprising a charger,
wherein the charger is electrically connected to the power storage device, and
wherein the charger comprises an antenna.
