1. A stabilized OLED device for emitting light of a specific color, comprising:

  • a) a metallic anode and a metallic cathode spaced from the metallic anode;

    b) a light-emitting layer including a host and a dopant disposed between the anode and the cathode, the dopant selected to produce light having a spectrum containing light of the specific color;

    c) a stabilizer provided in one of the device layers which improves the useful lifetime of the OLED device, wherein the stabilizer has an emission spectrum different from that of the light-emitting layer, and d) wherein one of the electrode layers is semitransparent and the other one is substantially opaque and reflective such that the stabilized OLED device forms a microcavity that emits a narrow blue_band light.
