Abstract:
1. A light emitting device comprising: a supporting substrate; a back electrode formed on the supporting substrate; a transparent electrode provided so as to face the back electrode; and luminescent particles provided between the back electrode and the transparent electrode, the luminescent particles being connected electrically to the back electrode and the transparent electrode, wherein the back electrode has recesses in a surface thereof facing the transparent electrode and the back electrode is provided along recesses formed in the supporting substrate, wherein a depth of the respective recesses of the back electrode is smaller than an average particle diameter of the luminescent particles, and wherein when a plane contacting an edge of the respective recesses is defined as a reference plane, and a width of the respective recesses of the back electrode is defined as a maximum dimension of an opening of the respective recesses defined by a contact point between the reference plane and the edge, the width of the respective recesses of the back electrode is larger than the average particle diameter of the luminescent particles.
