Patent attributes
An ink jet method known as a method for selectively forming a layer made of a polymeric organic compound is advantageous in that a layer containing an organic compound can be separately colored for emitting light of three colors (R, G, B) at a time. However, this ink jet method is disadvantageous in its poor film formation accuracy, and therefore, it is difficult to control the formation of the film for obtaining the uniformity. As a result, the obtained film is likely to have unevenness. In the present invention, an layer containing an organic compound is formed on the entire surface of a lower electrode connected to a thin film transistor by application. After forming an upper electrode on the lower electrode, an layer containing an organic compound is etched in a self-aligned manner by plasma etching using the upper electrode as a mask so as to allow the selective formation of an layer containing an organic compound. Furthermore, for connection with the upper electrode, the electrical connection is achieved by using an adhesive containing a conductive particle or a paste. Furthermore, a material emitting white light or a material emitting monochromatic light is used as the layer containing an organic compound. The full-color display is achieved by combining the layer containing an organic compound with a color conversion layer or a colored layer.
