PURPOSE:To realize a thin type structure and concurrently ensure the repeatability of various types of light color on a luminous screen without any irregularity. CONSTITUTION:Electric discharge channels 2b separated from each other with divisions 2a and having electrodes 3 at both ends are laid in parallel like a blind in space between opposite front and rear plates 1 and 2. The internal side of each channel 2b is coated with a phosphor 6 emitting a different color of light. Also, the channel 2b is internally filled with electric discharge medium gas, and the plates 1 and 2 are sealed, so as to keep airtightness. In this case, the plate 1 acts as a luminous screen allowing the emission of light, and a light diffusion plate 7 is laid at a micro distance from the screen. According to this construction, a luminous screen having a thin structure and a uniform color mixture can be provided. |
