Abstract:
1. A patterning apparatus for an electroluminescent display which comprises: a molding roller; a molding plate provided at the surface of the molding roller and containing a plurality of convex portions and concave portions the convex portions defining lands having a surface which contains a plurality of minute indentations; a polymer supplying roller positioned to engage with the lands of the convex portions of the molding plate for applying an electroluminescent material only to the lands of the molding plate via rotational movements of both the polymer supplying roller and the molding roller, wherein the molding plate applies the electroluminescence material disposed on the lands of the molding plate to an adjacent substrate via the rotational movement of the molding roller and a linear movement of the adjacent substrate, and the adjacent substrate includes a pixel electrode forming a pixel pattern and a plurality of barrier ribs positioned to receive the electroluminescence material therebetween for preventing the electroluminescent material from spreading, at least one barrier rib including a neck and a head having a larger width than the neck whereby a portion of the head overlaps an edge of the pixel electrode; and a heating device positioned to heat, to a predetermined temperature, the electroluminescent material formed on the substrate.
