Abstract
An organic EL display and fabricating method thereof enable a reduction in a process time by simplifying a fabricating process in a manner that a pattern of a single insulating layer is formed so as to have both functions of insulator and separator, increase an aperture ratio, and reduce a product cost. A plurality of stripe type first electrodes are provided on a transparent substrate, an insulating layer pattern is stacked on the transparent substrate and the first electrodes so as to cross with the first electrodes, a half tone pattern of insulator is stacked on the transparent substrate between the insulating layer pattern and between the first electrodes, a plurality of organic light-emitting layers are provided on a plurality of the first electrodes, respectively, and a plurality of second electrodes are provided on a plurality of the organic light-emitting layers
