Abstract: A diffuse reflective article is provided including a diffuse reflector of light positioned within a structure defining an optical cavity. The diffuse reflector is a nonwoven sheet containing a plurality of inter-fiber and intra-fiber pores of optimal light scattering dimension. Also provided is an optical display, including: (i) a structure defining an optical cavity; (ii) a light source positioned within the optical cavity; (iii) a display panel through which light from the light source passes; and (iv) a diffuse reflector positioned within the optical cavity for reflecting light from the light source toward the display panel, wherein the diffuse reflector is a nonwoven sheet containing a plurality of inter-fiber and intra-fiber pores of optimal light scattering dimension.

Abstract: The present invention relates to a process for forming an organic electronic device comprising at least two organic layers, said process comprising (a) applying a first organic layer comprising a first organic material by a method selected from vapor deposition and liquid deposition from a first organic liquid medium; (b) applying a second organic layer comprising a photoactive compound directly over at least a portion of the first organic layer by liquid deposition from a second organic liquid medium, wherein the first organic material is sparingly soluble in the second organic liquid medium.
