Abstract:
A light-emitting element that includes a fluorescent material and has a high emission efficiency is provided. A light-emitting element in which a delayed fluorescence component due to TTA accounts for a high proportion of emissive components is provided. A novel light-emitting device with a high emission efficiency and a low power consumption is provided. A light-emitting element includes an anode, a cathode, and an EL layer. The EL layer includes a light-emitting layer including a host material and an electron-transport layer including a first material in contact with the light-emitting layer. The LUMO level of the first material is lower than that of the host material. The proportion of a delayed fluorescence component due to TTA is greater than or equal to 10 percent of the light emission from the EL layer. The proportion of the delayed fluorescence component due to TTA may be greater than or equal to 15 percent of the light emission.

Claim (Index 8):
The light-emitting element according to  claim 1 ,\n wherein the first EL layer comprises a first hole-transport layer in contact with the first light-emitting layer, wherein the first hole-transport layer comprises a second material, and wherein a triplet excitation energy of the second material is higher than the triplet excitation energy of the substance that has the highest triplet excitation energy among the materials contained in the first light-emitting layer by greater than or equal to 0.2 eV.
