To provide an electrical apparatus which is thin and light, and has flexibility.

An electrical apparatus includes a first substrate and a second substrate arranged facing each other across a function element, a first electrode (back-side electrode) provided on a side closer to the first substrate than to the function element, a second electrode provided on the second substrate and electrically connected to the first electrode, and the function element and an electronic component for driving the function element provided in an area in which the first substrate and the second substrate overlap and which is sandwiched between the first electrode and the second electrode.
