| 摘要 | An organic EL device including: a substrate; an anode disposed on the substrate; a functional layer disposed on the anode, the functional layer containing a light-emitting layer; an electron transport layer disposed on the functional layer, the electron transport layer containing organic compound-containing material; and a cathode disposed on the electron transport layer so as to be in contact with the electron transport layer, the cathode being light-transmissive. The electron transport layer has a relative permittivity of no less than 2 and no greater than 10 when supplied with an AC voltage having a frequency of 1 MHz. | ||

| 主权项 | 1. An organic electroluminescence (EL) device, comprising: a substrate; an anode disposed on or above the substrate; one or more functional layers disposed on or above the anode, the one or more functional layers including a light-emitting layer; an electron transport layer disposed on or above the one or more functional layers, the electron transport layer containing organic compound-containing material; and a cathode disposed on the electron transport layer and in contact with the electron transport layer, the cathode being light-transmissive, wherein the electron transport layer has a relative permittivity of no less than 2 and no greater than 10 when supplied with an AC voltage having a frequency of no less than 1 MHz and no greater than 1 GHz, and the electron transport layer includes a degraded layer in which indium or oxygen penetrates the electron transport layer, a depth of the degraded layer being at most equal to 15 nm. | ||
