Light emitting element

A light emitting element comprising:

• a first electrode;
• a second electrode disposed on the first electrode;
• and
• a first emission part, a second emission part, and a third emission part which are disposed between the first electrode and the second electrode and sequentially stacked, wherein
• at least one of the first emission part, the second emission part, and the third emission part comprises:
• a first emission layer;
• and
• a second emission layer disposed on the first emission layer,
• the first emission layer comprises a first host and a first dopant,
• the second emission layer comprises a hole transport host different from the first host, an electron transport host, and a second dopant,
• a first hole mobility of the first host is in a range of about 5.0×10−6 cm2/V·s to about 1.0×10−3 cm2/V·s,
• a second hole mobility of a host mixture including the hole transport host and the electron transport host is in a range of about 1.0×10−6 cm2/V·s to about 1.0×10−4 cm2/V·s, and
• the first hole mobility is larger than the second hole mobility.
