Abstract: A display device includes pixels including a light-emitting element, and an initialization transistor connected between an anode electrode of the light-emitting element and a first initialization power line to which a voltage of initialization power is supplied, and turned on when an initialization scan signal is supplied, and an initialization scan driver which supplies the initialization scan signal. The initial scan driver supplies an i-th (i is a natural number) initial scan signal to overlap an (i?1)-th initial scan signal, and supplies an (i+1)-th initial scan signal so as not to overlap the i-th initial scan signal, and the initialization scan signal is set to a gate-on voltage.

Abstract: Disclosed herein is nanoemulsion prepared by emulsifying main metabolites of ginseng saponin obtained by conversion of glucose, i.e. compound K (20-O-?-D-glucopyranosyl-20(S)-protopanaxadiol), ginsenoside F1 (20-O-?-D-glucopyranosyl-20(S)-protopanaxatriol) and compound Y (20-O-[?-L-arabinopyranosyl(1?6)-?-D-glucopyranosyl]-20(S)-protopanaxadiol); and admixture-thereof, in fine emulsion or liposome with dermotropic emulsifier by nano-emulsification; and having enhanced skin penetration, so to be effective in promoting proliferation of fibroblast and biosynthesis of collagen.
