Abstract
Improvements in alternating current plasma display panels are disclosed including an imperforate intermediate structure in such a panel which provides both the function of a separator between the front and back plates (layers or structures) of the panel and the function of cross talk reducing barriers between cells of the panel. The structure includes spacing bosses which extend from the barrier structure and engage the front transparent dielectric plate, and sidewall portions intermediate adjacent pairs of spacing bosses which are separated somewhat from the front dielectric plate to provide a gas and ion passing gap between adjacent cells. In one preferred form, the sidewalls blend into a generally flat bottom wall within each cell. The sidewalls and bottom wall have a smooth or specular surface and may be coated with a reflective material to enhance cell brightness.
