Abstract: The present invention provides a mirror display that has improved design aesthetics and makes it possible to sufficiently improve visibility in mirror mode in dark environments. The mirror display according to the present invention includes a half mirror plate having a half mirror layer, a display device, a case, and an auxiliary illumination unit that includes an auxiliary light source. The case supports at least the half mirror plate and the display device and includes an outer frame that covers an edge of a front surface of the half mirror plate when viewed in a plan view from a viewing side. The display device is arranged on a rear side of the half mirror plate. The auxiliary light source is arranged on the rear side of the half mirror plate, the display device, or the outer frame. The auxiliary illumination unit is controlled separately from the display device and emits light towards the viewing side when the mirror display is in mirror mode.

Abstract: A stack-type photovoltaic element with improved conversion efficiency having an intermediate layer and a method of manufacturing the same are provided. A stack-type photovoltaic element according to the present invention includes a first photovoltaic element portion (a) and a second photovoltaic element portion from a substrate side, as well as at least one intermediate layer between the first photovoltaic element portion and the second photovoltaic element portion. The intermediate layer is formed from a metal oxide film having an oxygen atom concentration/metal atom concentration ratio not lower than 0.956 and not higher than 0.976.

Abstract: Disclosed is a stacked photovoltaic element, including: a first photovoltaic element portion including at least one photovoltaic element, stacked over a substrate; an intermediate layer made of a metal oxide, stacked over the first photovoltaic element portion; a buffer layer in an amorphous state, stacked over the intermediate layer; and a second photovoltaic element portion including at least one photovoltaic element, stacked over the buffer layer, wherein a conductive layer of the second photovoltaic element portion in contact with the buffer layer is a microcrystalline layer.

Abstract: A cosmetic comprises an alkyl phosphate represented by the formula (I): ##STR1## in which R.sub.1 and R.sub.2 independently represent hydrogen atom or an alkyl group having from 1 to 36 carbon atoms, and R.sub.3 represents an alkyl group having from 1 to 36 carbon atoms, and a cosmetic powder.The cosmetic is water-repellent in nature, unlikely to break by sweat and is readily spread on the skin with improved softness due to incorporation of the alkyl phosphate.The cosmetic is prepared by first mixing the cosmetic powder and the alkyl phosphate dissolved in an organic solvent under heating conditions. Subsequently, the solvent is distilled off to form an alkyl phosphate coating on the indivisual particles. The coated particles are mixed with other cosmetic ingredients.
