  • Patent number: 7056193
    Abstract: The present invention includes a method of producing a planar display device by application of the method. The fine partition walls are formed on the surface of a second substrate that constitutes a second panel 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. The maximum particle diameter of the abrasive is not more than ½ times the width of the fine partition walls, and the mean particle diameter of the abrasive is not more than ? times the width of the fine partition walls.
