  • Publication number: 20100295036
    Abstract: There is provided a process for forming an organic electronic device wherein a TFT substrate having a non-planar surface has deposited over that substrate a planarization layer such that a substantially planar substrate, or planarized substrate, is formed. A multiplicity of thin first electrode structures having a first thickness and having tapered edges with a taper angle of no greater than 75° are formed over the planarized substrate. A multiplicity of active layers is formed over the planarized substrate. Then a buffer layer is formed by liquid deposition of a composition comprising a buffer material in a first liquid medium. The buffer layer has a second thickness which is at least 20% greater than the first thickness. A chemical containment pattern defining pixel openings is then formed over the buffer layer. A composition comprising a first active material in a second liquid medium is deposited into at least a portion of the pixel openings. Then a second electrode is formed.
