Abstract

A light emitting device includes a reflective sheet having a light reflecting face; a plurality of oblong flexible substrates; and a plurality of light emitting sections disposed at intervals on a face of each of the flexible substrates. The plurality of the flexible substrates comprises a first group of flexible substrates that are lined up at intervals in a first direction and a second group of flexible substrates that are lined up at intervals in a second direction such that the flexible substrates of the second group intersect the flexible substrates of the first group. The first group and the second group are layered in a thickness direction and adhered to at least one face of the reflective sheet so as to expose the plurality of light emitting sections.
