Abstract
A display device consisting of a multi-color light emitting layer and method of depositing the multi-color light emitting layer over a glass substrate are provided. The display device consists of multiple light emitting materials deposited over a glass substrate in coplanar relationship to each other. The method provides depositing one light emitting polymer material over one portion of the glass substrate and depositing other light emitting polymer materials over other portions of the glass substrate, such that the multiple light emitting polymer materials are deposited in a coplanar relationship to each other. The light emitting polymer materials are deposited using flexographic mats, the relief portion of which have patterns corresponding to the respective portions of the glass substrate being covered by the light emitting polymer materials being deposited.
