An electrooptical device having a plurality of light-emitting regions includes a substrate, a bank disposed in a region other than the light-emitting regions on the substrate so as to surround the light-emitting regions, and a functional layer disposed in openings surrounded by the bank. In another aspect, a composition comprises particles of amorphous atorvastatin and a core. The window located behind the beam splitter, the lens element group and the beam splitter being located on a line with the window. The drum is rotated to enable cleaning of filter media. The deformation fields are applied to the calculated phase images.
