  • Patent number: 9105855
    Abstract: There has been a problem that difference in refractive index between an opposite substrate or a moisture barrier layer provided thereover, and air is maintained large, and light extraction efficiency is low. Further, there has been a problem that peeling or cracking due to the moisture barrier layer is easily generated, which leads to deteriorate the reliability and lifetime of a light-emitting element. A light-emitting element comprises a pixel electrode, an electroluminescent layer, a transparent electrode, a passivation film, a stress relieving layer, and a low refractive index layer, all of which are stacked sequentially. The stress relieving layer serves to prevent peeling of the passivation film. The low refractive index layer serves to reduce reflectivity of light generated in the electroluminescent layer in emitting to air. Therefore, a light-emitting element with high reliability and long lifetime and a display device using the light-emitting element can be provided.

  • Patent number: 9082960
    Abstract: A synthetic antiferromagnet serving as a reference layer for a magnetic tunnel junction is a laminate with a plurality of “x+1” magnetic sub-layers and “x” non-magnetic spacers arranged in an alternating fashion, with a magnetic sub-layer at the top and bottom of the laminated stack. Each spacer has a top and bottom surfaces that interface with adjoining magnetic sub-layers generating antiferromagnetic coupling between the adjoining sub-layers. Perpendicular magnetic anisotropy is induced in each magnetic sub-layer through an interface with a spacer. Thus the dipole field exerted on a free layer is substantially reduced compared with that produced by a conventional synthetic antiferromagnetic reference layer. Magnetic sub-layers are preferably Co while Ru, Rh, or Ir may serve as non-magnetic spacers.
