| 摘要 | Provided is a light emitting device having a mechanism capable of efficiently dissipating heat kept in the device to the outside. The light emitting device includes: a first substrate including a heat radiation layer; a second substrate exhibiting light transmittance; and a plurality of organic EL elements provided, between the first substrate and the second substrate to emit light toward the second substrate. The second substrate includes fibrous, thermally conductive wires dispersively arranged therein, and the thermally conductive wires have a diameter of 0.4 μm or less and have a thermal conductivity higher than the remaining component of the second substrate excluding the thermally conductive wires. | ||
