Light emitting device, method of manufacturing the same, and manufacturing apparatus therefor

摘要

A light emitting device having high definition, a high aperture ratio, and high reliability is provided. The present invention achieves high definition and a high aperture ratio with a full color flat panel display using red, green, and blue color emission light by intentionally forming laminate portions, wherein portions of different organic compound layers of adjacent light emitting elements overlap with each other, without depending upon the method of forming the organic compound layers or the film formation precision.

主权项

1. A light emitting device comprising:
a first substrate and a second substrate; a first transistor and a second transistor over the first substrate; an insulating film over the first transistor and the second transistor; a first electrode over the insulating film, and electrically connected to the first transistor through a first contact hole in the insulating film; a second electrode over the insulating film, and electrically connected to the second transistor through a second contact hole in the insulating film; an insulator portion covering an edge portion of the first electrode and an edge portion of the second electrode, and filling a balance of the first contact hole; a first EL layer on and in contact with the first electrode and the insulator portion; a second EL layer on and in contact with the second electrode and the insulator portion; a first colorization layer over the first substrate and under the second substrate so that the first colorization layer overlaps the first EL layer and is interposed between the first EL layer and the second substrate; a second colorization layer over the first substrate and under the second substrate so that the second colorization layer overlaps the second EL layer and is interposed between the second EL layer and the second substrate; and a shading portion between the first colorization layer and the second colorization layer, overlapping the insulator portion and interposed between the insulator portion and the second substrate, wherein the shading portion overlaps the first contact hole, and wherein the second substrate is capable of transmitting light so that an observer could perceive light emitted by the first EL layer and by the second EL layer from above the second substrate.
