If the disk of the spiral galaxies has a moderated value of the mean optical depth, the observed luminosity function should be corrected for the combined effect of the inclination and the opacity of the galactic disk. We obtain the corrected luminosity function for current models of opaque matter distribution.

Key words: ISM: dust,extinction – galaxies: luminosity function
