Claim 0:
1. A top-emitting subpixel structure comprising:
at least one bank structure disposed on a substrate and having reflective non-vertical surfaces defining a plurality of emissive areas of a subpixel configured to emit light of a first color; and
a plurality of emissive structures each of which located in each emissive area in the plurality of emissive areas, each emissive structure comprising:
a reflective bottom electrode disposed over the substrate;
an emissive layer disposed over the reflective bottom electrode;
a transparent top electrode disposed over the emissive layer; and
a filler layer disposed atop and in contact with the transparent top electrode, the filler layer having a refractive index substantially equal to a refractive index of the transparent top electrode, wherein:

the subpixel structure has a subpixel length and a subpixel width less than the subpixel length,
a ratio of the subpixel length to the subpixel width defines a subpixel aspect ratio,
each emissive area in the plurality of emissive areas has an emissive area length and an emissive area width less than the emissive area length,
a ratio of the emissive area length to the emissive area width defines an emissive area aspect ratio,
the subpixel length defines a primary axis when the subpixel aspect ratio is greater than the emissive area aspect ratio, otherwise the emissive area length defines the primary axis,
at least a majority of the plurality of emissive areas is arranged successively widthwise along a secondary axis perpendicular to the primary axis, and
the plurality of emissive areas is arranged in a staggered pattern.
