The present invention provides novel amine compounds useful as electron-transporting materials to be incorporated in organic electro-luminescence devices. More particularly, the present invention provides an organic electro-luminescence device (organic EL device) which can find wide application in various display units, requires a low applied voltage and exhibits a high luminance and an excellent stability.

In a plasma surface treating method, a sample to be treated is supported on a first electrode within a vacuum vessel and a second electrode is caused to confront the first electrode. Active species of negative ions are then generated by means of a direct current glow discharge produced in an abnormal glow discharge region and are subsequently impinged upon a surface of the sample to induce a chemical reaction with the sample.

An optical data medium is disclosed from which information recorded to the surface is reproduced by focusing a laser thereon and reading the light reflected from the data surface. The medium includes a first transparent layer having a top data surface for carrying data, and a second transparent layer having a bottom data surface for carrying data. A semi-transparent layer is inserted between the first and second transparent layers. When the laser is focused on the top data surface, the data carried therein is reproduced, and when the laser is focused on the bottom data surface, the data carried therein is reproduced.
