Oled display with optical interconnect between driving plane and display plane

摘要

A semiconductor device comprising: circuits provided over a plurality of glass substrates, wherein glass substrates of the plurality of glass substrates each have both or either of a light emitting element and a photo-detecting element, and wherein a transmission of a signal between the circuits provided over the plurality of glass substrates is performed by converting an optical signal emitted from the light emitting element into an electrical signal at the photo-detecting element, characterized in that the light emitting element emits light having directivity as the optical signal.
