Light-emitting element and electronic device

A light-emitting element comprising:

• an anode;
• a hole-injection layer over the anode;
• a hole-transport layer over the hole-injection layer;
• a light-emitting layer over the hole-transport layer;
• and
• a cathode over the light-emitting layer,
• wherein the hole-injection layer comprises an organic compound and molybdenum oxide,
• wherein the organic compound is represented by a formula (G1),
• wherein Ar represents an aryl group having 6 to 70 carbon atoms,
• wherein R0 represents a substituent represented by a formula (g1) and is bonded to a carbon atom represented by either α or β,
• wherein R8 represents any one of hydrogen, an alkyl group having 1 to 6 carbon atoms, an aryl group having 6 to 15 carbon atoms, and a substituent represented by a formula (g2) and is bonded to a carbon atom represented by either γ or δ,
• wherein X1 and X2 individually represent oxygen or sulfur, and
• wherein R1 to R7 and R9 to R15 individually represent any one of hydrogen, an alkyl group having 1 to 6 carbon atoms, and an aryl group having 6 to 15 carbon atoms.
