Abstract

An electronic device includes a substrate, a functional element formed on the substrate, an electrolytic element provided on at least one of a side of the substrate on which the functional element is formed and a side of the substrate opposite to the side on which the functional element is formed, configured including a solid-state electrolyte layer and a pair of electrodes for holding the solid-state electrolyte layer in between, and capable of applying electrolysis to water, and a sealing member for sealing the functional element and the electrolytic element.

Claims

1. An electrophoretic device comprising:

a substrate including;

a first side; and

a second side opposite to the first side;
