Abstract
A light emitting display comprising a first electrode layer on a substrate. The electrode layer is patterned to form a plurality of laterally spaced apart strips in a first direction. A plurality of spacedly disposed light emitting organic elements with a second electrode layer atop are disposed on the first electrode layer in a second direction. An undercut structure made of an undercut pattern transfer layer and an overlaying pattern transfer layer. The undercut structure is disposed between the plurality of spacedly disposed light emitting organic elements. A light emitting display having a color isolation well. The color isolation well is characterized by a first well layer and a second well layer in which the first well layer matches a property of an emissive polymer or small molecule dye held by the well whereas the second well layer does not match the property.
