Plasma display panel having bumps on barrier ribs
A plasma display panel and method are provided. The method includes that a first substrate is provided and elongated electrodes are formed on the first substrate. Then, an overcoat layer is formed on the elongated electrodes and the first substrate. Next, by means of screen print, a shaped layer is formed on the overcoat layer. Screen print is applied again to form bumps on the shaped layer. A second substrate is also provided. The second substrate is extended paralleled with the first substrate so as to define a discharge space between the substrates after combining the two substrates. Bumps are provided between the first and second stripe ribs so as to define passages to let air can flow in the discharge space. By the mentioned processes, bumps are provided between the first and second stripe ribs so as to define passages for drawing air. The process is simple for alignment.
