"9. The method of claim 1, further comprising:

depositing a second ink from an inkjet printhead to the first organic buffer layer, the second ink being defined by a second carrier and dissolved or suspended film-forming organic material; and

driving off（除去）the second carrier to form an organic material layer on the first organic buffer layer;

wherein the first reflective electrode is semi-transparent and the first organic buffer layer exhibits a refractive index that is intermediate between a refractive index（屈折率）of the substrate and a refractive index of the organic material layer."

"Referring to Figure 2 A, a dielectric stack mirror 100, which can be incorporated into（組み込む）an apparatus according to embodiments of the subject invention（対象発明、本発明）, can include alternating layers of dielectric material (37. 39 ) having different indexes of refraction（屈折率）(n). For example, the higher n material 37 can be Ta₂O₅, and the lower n material 39 can be SiO₂, though embodiments are not limited thereto（限定されない）. Each layer (37. 39) can have a thickness of from about 10 nm to about 100 nm（から～の範囲の厚さ）. and there can be from 1 to 40 (in quantity) of each type of layer."

"The present invention recognizes the problem and also recognizes that the emission from a microcavity OLED device is highly angle dependent. The resonance condition of a microcavity OLED device can be described by Eq. 1:
2Σn _i L _i cos θ_i+(Q _m1 +Q _m2)λ/2π=mλ　　Eq. 1
wherein:

• n_i is the refractive index（屈折率）and L_i is the thickness of the ith sublayer in organic EL element;
• θ_i is the angle of the light in the ith（i番目の；＊i-thとしてない）sublayer measured from the normal to（対する法線）the plane of the OLED device;
• Q_m1 and Q_m2 are the phase shifts in radians at the two organic EL element-metal electrode interfaces（境界面での；＊at）, respectively;
• λ is the resonant wavelength to be emitted from the device; and
• m is a non-negative integer.
  Note that the θ_i for the different sublayers (and including the angle of the light emitted outside of the device) are not independent but are related to each other via Snell's Law: n_i sin θ_i=n_j sin θj."
