Multilayer electronic substrate

A multilayer electronic substrate, comprising:

• a first substrate;
• a second substrate on the first substrate, wherein a surface of the first substrate faces a surface of the second substrate;
• a first connector on the surface of the first substrate, wherein the first connector is configured to electrically connect to a first wire of the first substrate;
• a second connector on the surface of the second substrate, wherein
• the second connector is configured to electrically connect to a first wire of the second substrate, and
• the second connector is directly connected to the first connector;
• and
• a flexible wiring member, wherein
• the flexible wiring member includes:
• a first end that is electrically connected to a second wire of the first substrate;
• and
• a second end that is electrically connected to a second wire of the second substrate, and
• the second wire of the first substrate is electrically connected to the second wire of the second substrate via the flexible wiring member.
