A collapsible backlight system for providing wide area back lighting for display assemblies, and adapted to remain fully assembled in transition between storage, transportation, setup and use. A flexible sheet includes a plurality of sheaths adapted to substantially protectively envelop individual elongated light sources. The collapsible backlight system has expanded and collapsed configurations. In expanded configuration, the flexible sheet is generally planar and the elongated light sources are spatially dispersed. In collapsed configuration, the elongated light sources are maintained proximal to each other in generally parallel fashion, and the collapsible backlight system can be carried and transported in compact form without causing damage to the elongated light sources. The flexible sheet may have front and rear layers, each such layer possessing selected optical qualities such as translucency, reflectivity and diffusivity, depending on the desired application. Discrete interstices between such layers may define the sheaths which substantially protectively envelope the elongated light sources.
