    • To provide a laser oscillator that has an oscillation wavelength in a visible region, and can enhance a conversion efficiency of photon output, and further suppress power consumption. The laser oscillator comprises a light emitting element formed on a substrate, and an optical resonator. The light emitting element includes a luminescent layer, an anode and a cathode, in which the luminescent layer is interposed between the anode and the cathode. The luminescent layer comprises a host material and a phosphorescent material, which is dispersed into the host material at a concentration of not smaller than 10 wt %. The anode and the cathode comprises a light transmitting property. In luminescence from the excimer state of the phosphorescent material, unidirectional light that intersects with the luminescent layer is amplified by the optical resonator.

    • When a light-emitting element having an intermediate conductive layer between a plurality of light-emitting layers is formed, the intermediate conductive layer can have transparency; and thus, materials are largely limited and the manufacturing process of an element becomes complicated by a conventional method. A light-emitting element according to the present invention is formed by sequentially stacking a pixel electrode, a first light-emitting layer, an intermediate conductive layer (including an electron injecting layer and a hole-injecting layer, one of which is island-like), a second light-emitting layer and an opposite electrode. Therefore, the present invention can provide a light-emitting element typified by an organic EL element in which a range of choice of materials that can be used as the intermediate conductive layer is broadened extremely, and which can realize a high light-emitting efficiency, a low power consumption and a high reliability, and further a display device using the light-emitting element.
