Abstract
The invention contemplates anisometrically shaped carbon-containing particles for use as the particles of a liquid light valve suspension, films and light valves. The anisometric carbon-containing particles are crystalline or amorphous particles and can have various geometrical shapes including, for example, flakes. The above object is achieved by carefully controlling the size and shape of such particles.
