摘要： An object of the present invention is to realize an OLED capable of attaining high luminescence luminance and easy to manufacture. An organic electroluminescence device (1) of the present invention includes a luminescent layer (7) between an anode (3) and a cathode (9). The luminescent layer (7) contains an organic luminescent material. The organic electroluminescence device includes: a hole transportation layer (6) formed between the anode (3) and the luminescent layer (7); a metal nano particle layer between the anode (3) and the hole transportation layer (6), the metal nano particle layer being a layer in which metal nano particles (5) are dispersedly distributed. The metal nano particle layer is such that gaps between the metal nano particles (5) dispersedly distributed are filled with a hole transportation material. The metal nano particles (5) causes resonance with excited electrons in the luminescent layer (7), thereby reinforcing the luminescence by surface plasmon.
