LIQUID CRYSTAL DISPLAY CONTAINING AN ADDITIONAL BROAD ANGLE BACK SCATTERING MATERIAL

摘要

A display is disclosed which contains a liquid crystal panel, a dichroic reflecting layer, and additionally contains a second wide angle back scattering material. Preferably, the second scattering material acts as a Lambertian scatterer. The display may include an external source of front-lighting, and, of course, contains suitable electrodes and substrates, and optionally contains anti-reflection coatings. The advantage of this display is that it is easily readable by an observer over a wide range of ambient lighting conditions. The outstanding readability is provided because the display has excellent color contrast.
