Abstract

A display device includes an illumination medium, a display medium, and a conductor. The illumination medium includes a light-emitting element and a connection portion. The light-emitting element includes a first electrode and a second electrode and emits light with the use of power supplied between the first electrode and the second electrode. The connection portion is electrically connected to at least one of the first electrode and the second electrode. The display medium includes a terminal, relay wiring, and an electro-optical element. The relay wiring is electrically connected to the terminal. The electro-optical element controls light that is irradiated by and comes from the illumination medium according to electric energy supplied to the electro-optical element. The conductor electrically connects the relay wiring and the connection portion.

Claims (34)

1. A display device comprising:

an illumination medium comprising:
