ABSTRACT:
A display having a filter disposed on, or in, a portion of the substrate is described. The filter is generally a red filter such that light passing through the filter will produce a red colored light. The filter is comprised of cadmium sulfoselenide in a 62/38 composition (CdS.sub..62 Se.38). The light is generated by a phosphor element which will emit a compatible color light. Other light emitting phosphors, such as green and blue, are also utilized without a filter to provide a multi-colored display.
