ABSTRACT:
It is an object of the present invention to provide a display device preventing the external invasion of water and/or oxygen and preventing the deterioration of a luminous element due to these invading substances and to provide a production method including simple production steps for producing the display device. The invention provides a display device having a sealing material on the rim of an exposed interlayer insulator for preventing the invasion of water and/or oxygen from the interlayer insulator. Further, the invention provides a display device having a barrier body on an exposed interlayer insulator for preventing the invasion of water and/or oxygen from the interlayer insulator. Furthermore, the application of droplet discharge technique in production steps for producing the display device can eliminate a photolithography step such as exposing and developing. Thus, a method of producing a display device having an improved yield is provided.
