EL display device and a method of manufacturing the same
Patent 7521722 Issued on April 21, 2009. Estimated Expiration Date: October 6, 2026. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
To provide a high throughput film deposition means for film depositing an organic EL material made of polymer accurately and without any positional shift. A pixel portion is divided into a plurality of pixel rows by a bank, and a head portion of a thin film deposition apparatus is scanned along a pixel row to thereby simultaneously apply a red light emitting layer application liquid, a green light emitting layer application liquid, and a blue light emitting layer application liquid in stripe shapes. Heat treatment is then performed to thereby form light emitting layers luminescing each of the colors red, green, and blue.
