Patent ID: 8192579

Claim:
An emissive layer formation method for transferring, to a substrate, an emissive layer provided on a transfer element, wherein the substrate includes a plurality of wirings arranged side by side to extend in a predetermined direction, and a protective insulating layer formed between adjoining pixels and formed as a rib protruding from the substrate, and the emissive layer on the transfer element is pressed onto the protective insulating layer and affixed through pressure to a top surface of the rib, thereby the emissive layer transferred to the substrate is confined to an area which is surrounded by the rib of the protective insulating layer, the substrate and the transfer element, and diffusion of the emissive layer is controlled by the area, thereby transferring the emissive layer in the area; wherein a color filter layer for filtering light coming from the emissive layer is formed corresponding to the emissive layer.
