Abstract

A method of making an electroluminescent device consisting of a layer of organic electroluminescent material between anode and cathode layers includes the step, after forming the layers on a transparent substrate, and after encapsulation of the device in a hermetically sealed packaage containing an inert atmosphere, of patterning the device using ultraviolet light. The device is exposed to ultraviolet light through a mask which is the negative of the desired pattern for the electroluminescent device. Areas of the device which receive ultraviolet light do not luminesce as brightly as areas which are shielded from the ultraviolet light. After exposure to the ultraviolet light, the device can be coated with an ultraviolet barrier layer, or placed in a structure which shields it from ultraviolet barrier layer, or placed in a structure which shields it from ultraviolet light thus preventing further degradation of the electroluminescent properties.
