Abstract
A method of forming fine partition walls by which fine partition walls with stable shape can be formed with good processing accuracy and at good grinding efficiency by a jet processing technique, a method of producing a planar display device by application of the method, and an abrasive for jet processing to be used in these methods, are disclosed. The fine partition walls are formed on the surface of a substrate by jet processing using an abrasive comprised of a powder of calcium carbonate coated with silicone on the surfaces thereof. Each of the particles constituting the abrasive has a three-dimensional shape comprised of a stack of different-sized triangular or more-angular polygonal layers.
