摘要 |
An organic compound having a high T1 level is provided. An element emitting phosphorescence in the blue and green regions is provided. An organic compound having a high glass-transition temperature is provided. A light-emitting element, a light-emitting device, an electronic appliance, or a lighting device having high heat resistance is provided. A light-emitting element includes at least a hole-transport layer, a light-emitting layer, and an electron-transport layer between an anode and a cathode. An anthracene compound represented by General Formula (G1) is contained in at least one of the hole-transport layer, the light-emitting layer, and the electron-transport layer.; |

1. A light-emitting element comprising:
an anode; a cathode; a hole-transport layer; a light-emitting layer; and an electron-transport layer, wherein the hole-transport layer, the light-emitting layer, and the electron-transport layer are provided between the anode and the cathode, wherein the light-emitting layer comprises an anthracene compound represented by General Formula (G1) and a phosphorescent compound, and wherein one of the hole-transport layer and the electron-transport layer comprises the anthracene compound represented by General Formula (G1), wherein α represents a substituted or unsubstituted m-phenylene group or a substituted or unsubstituted 3,3′-biphenyldiyl group, wherein Ar represents any of a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted carbazolyl group, a substituted or unsubstituted dibenzothiophenyl group, a substituted or unsubstituted dibenzofuranyl group, a substituted or unsubstituted triphenylenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted phenanthrenyl group, a substituted or unsubstituted fluorenyl group, a substituted or unsubstituted pyridyl group, a substituted or unsubstituted pyrimidyl group, a substituted or unsubstituted dibenzoquinoxalinyl group, a substituted or unsubstituted benzimidazolyl group, and a substituted or unsubstituted benzoxazolyl group, and wherein in the case where a substituent is bonded to Ar, the substituent is a phenyl group, a biphenyl group, or an alkyl group having 1 to 6 carbon atoms. |
