PROBLEM TO BE SOLVED: To provide a luminescent layer compound usable as a host material with an emission wavelength shifted to the longer wavelength. SOLUTION: The luminescent layer compound includes, in an at least dimeric form, a carbazole skeleton having one or more fluorine atoms in positions 3 and 6, represented by formula (1) (wherein at least either R3 or R6 is F, and the others are hydrogen atoms).
