Patent ID: 7646010

Claim:
A light-emitting element comprising: a first electrode and a second electrode, and a first layer, a second layer and a third layer formed between the first electrode and the second electrode, wherein the first layer contains an anthracene derivative represented by a general formula (1) and a first substance that shows electron acceptability to the anthracene derivative, wherein the anthracene derivative represented by the general formula (1) and the first substance are mixed, wherein the second layer contains a light-emitting substance, wherein the third layer contains a second substance having electron mobility of 1×10 −6 cm 2 /Vs or more and a third substance that shows electron-donating property to the second substance, wherein R 1 to R 8 are individually any one of hydrogen and an alkyl group having 1 to 4 carbon atoms, or R 1 and R 2 , R 3 and R 4 , R 5 and R 6 , and R 7 and R 8 are individually bonded to form an aromatic ring, and wherein the bond of R 1 and R 2 , the bond of R 3 and R 4 , the bond of R 5 and R 6 , and the bond of R 7 and R 8 are independent of one another.
