| 摘要 |
The invention provides an organic electric field luminous element, comprising a first electrode, a luminous layer, a semi-transmitting second electrode, a middle layer, a semi-transmitting layer and a light-transmitting layer in order. The organic electric field luminous element also comprises a first resonator structure which resonates and ejects light ejecting from the luminescent layer between the first electrode and the second electrode, and a second resonator structure which resonates and ejects the light between the first electrode and the semi-transmitting layer. One fourth of peak value wavelength of light ejecting from the luminescent layer is set as t, and the refractive index of the light-transmitting layer is set as n. the thickness of the light-transmitting layer is set above 0.9*t/n and below 1.1*t/n. |
