ABSTRACT:
A top-emitting OLED device with improved off-axis viewing includes a substrate; a reflective, substantially opaque, and conductive anode including a metal or metal alloy or both formed over the substrate; at least one organic layer formed over the anode and including an electroluminescent material; a cathode including a semitransparent metallic layer provided over the organic layer wherein the semitransparent metallic layer includes a low reflectivity metal; an light transmissive layer provided over the cathode; and the cathode and light transmissive layer being selected to reduce the color shift with respect to an off-axis viewing angle.
