Zusammenfassung:The invention provides a light emitting layer host compound and an electron-blocking compound that have high excited triplet levels, and can completely confine the triplet excitons of phosphorescent material, for use as the material of a high-efficient organic electroluminescent device. The invention also provides a high-efficient, high-luminance organic electroluminescent device with the use of the compounds. The compound of the general formula (1) below has a triphenylsilyl group and a triarylamine structure, and the organic electroluminescent device includes a pair of electrodes and at least one organic layer interposed between the pair of electrodes, wherein the compound of the general formula (1) having a triphenylsilyl group and a triarylamine structure is used as constituent material of the at least one organic layer.
