Abstract
A flat, light-emitting discharge panel, such as for back lighting displays, has two parallel transparent glass plates which are spaced by rows of pyramid-shape pillars. The pillars are formed integrally with at least one of the plates. The space between the two plates contains a discharge gas at reduced pressure, the inner surface of the plates and the surface of the pillars being coated with a phosphor which emits light on discharge in the panel. The outer surface of one plate has a reflector which reflects emitted light through the panel to the display. The pillars have angled surfaces which reflect light out of the panel and which act as light guides.
