1. A flexible display apparatus, comprising:

  • a flexible base film;

    a flexible light emitting device formed on the base film, the light emitting device including a first electrode layer, a second electrode layer, and a light emitting layer disposed between the first and second electrode layers;

    a first outermost surface located on the light emitting device and forming a light emitting surface;

    a second outermost surface located on the base film and forming a rear surface; and

    an inorganic sealing layer including silicon nitride provided on the flexible light emitting device, and a polymer film provided on the inorganic sealing layer and forming the first outermost surface, with the polymer film being in contact with the inorganic sealing layer, whereinthe first outermost surface forming the light emitting surface has a hardness higher than a hardness of the second outermost surface forming the rear surface,wherein a roughness of the second outermost surface is greater than a roughness of the first outermost surface.
