摘要： [Object] To provide a light emitting element having a configuration in which a color change depending on the current density is less likely to occur. [Solution] A light emitting element includes: a structure in which an anode 51, an organic layer 70 containing an organic material and including a light emitting layer, and a cathode 52 are stacked. The light emitting layer includes, from a side of the anode to a side of the cathode, two or more light emitting regions configured to emit different colors of light. Each light emitting region contains a host material and a dopant material. An absolute value of an ionization potential of the host material contained in a light emitting region near to the cathode is larger than an absolute value of an ionization potential of the host material contained in a light emitting region near to the anode.
