Abstract
A display device comprising a body for housing first and second transparent members and a carrier that supports sources of light. The first member is spaced from the second member such that a first plenum chamber is formed between the first and second members. The carrier is spaced from the second member on a side of the second member opposite the first chamber such that a second plenum chamber is formed between the second member and the carrier. A spacer separates the carrier from the second member by a predetermined amount. The sources of light being directed at the first and second members and the first and second chambers. The first chamber is filled with optical particles to diffuse the light passing through. The carrier applies a load, via the spacer, on the second member such that the particles are maintained at a pressure.
