LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, AUTHENTICATION DEVICE, AND ELECTRONIC APPARATUS |
| 摘要 |
A light-emitting element includes an anode, a cathode, a light-emitting layer which is provided between the anode and the cathode and emits light in a wavelength range of 700 nm or more by conducting electricity between the anode and the cathode, and an electron transport layer which is provided between the light-emitting layer and the cathode, and includes a first electron transport layer located on the cathode side and a second electron transport layer located on the light-emitting layer side, wherein organic materials contained in the light-emitting layer, a hole injection layer, the first electron transport layer, and the second electron transport layer have a glass transition temperature Tg of 135° C. or higher or do not have a glass transition temperature. |

1. A light-emitting element, comprising:
an anode; a cathode; a light-emitting layer which is provided between the anode and the cathode and emits light in a wavelength range of 700 nm or more by conducting electricity between the anode and the cathode; a hole injection layer which is provided between the light-emitting layer and the anode; and an electron transport layer which is provided between the light-emitting layer and the cathode, and includes a first electron transport layer located on the cathode side and a second electron transport layer located on the light-emitting layer side, wherein organic materials contained in the light-emitting layer, the hole injection layer, the first electron transport layer, and the second electron transport layer have a glass transition temperature Tg of 135° C. or higher or do not have a glass transition temperature. |
