A photosensitive green composition for a color filter of a solid-state imaging element, contains a colorant (A), a binder resin (B), a photopolymerization initiator (C), a photopolymerizable monomer (D), an ultraviolet absorber (E), and a monofunctional thiol (F), wherein the colorant (A) contains C.I. Pigment Green 36 and/or C.I. Pigment Green 58.

Coloring composition for solid-state imaging element

A method is provided for forming a uniform light emitting medium layer by a relief printing method without occurrence of printing defects. The method includes producing an organic EL device containing a substrate having thereon a pixel electrode, pixel regions that are demarcated with a partition wall on the pixel electrode, a light emitting medium layer having a light emitting layer containing at least an organic light emitting material on the pixel regions, and a counter electrode facing the pixel electrode. The method can have a step of forming at least one layer constituting the light emitting medium layer by a relief printing method, and the ink used in the relief printing method being transferred from two or more adjacent relief patterns within one of the pixel regions and being integrated by flow thereof to form the light emitting medium layer.
