Abstract:
1. A light emitting device comprising: an insulating film formed over a substrate; a color filter formed over said insulating film, said color filter comprising at least first, second, and third coloring layers wherein the first coloring layer is located between the second and third coloring layers; a light emitting element comprising a conductive polymer and a light emitting layer comprising an organic compound wherein the conductive polymer and the light emitting layer are provided between first and second electrodes and over said first coloring layer; and a barrier layer covering ends of the first electrode, wherein a boundary region of coloring layers adjacent each other is formed, and wherein the barrier layer overlaps said boundary region, wherein the conductive polymer is formed over the barrier layer, and wherein a first portion of the conductive polymer formed in contact with the first electrode is thicker than a second portion of the conductive polymer formed over the barrier layer.
