US Patent 7279835 Plasma display panel and fabricating method thereof

A plasma display panel that prevents color mixture between adjacent cells is provided. The plasma display panel includes a plurality of discharge cells defined by a corresponding plurality of barrier ribs, and a phosphor layer formed on the bottom surface of the discharge cells and side surfaces of the barrier ribs. A ratio of the thickness of the phosphor layer formed on the side surface of the barrier ribs to the thickness of the phosphor layer formed on the bottom surface of the discharge is between approximately 0.8 and 1.3. A phosphor layer formed in this manner provides improved emission characteristics, and allows for a simplified, more cost effective manufacturing process.
