Claims
- 1. A method of making a liquid crystal display, the method comprising the steps of:
- providing first and second substantially transparent substrates;
- providing first and second polarizers;
- spin coating a diffusing material onto the second substrate, said diffusing material including a host material which is substantially transparent to at least one wavelength of visible light and a plurality of diffusing particles embedded therein;
- sandwiching a liquid crystal layer between the first and second substrates so that the diffusing material is located at a point between the second substrate and the liquid crystal layer whereby the diffusing material is positioned between the substrates; and
- locating the first and second polarizers so that the resulting display includes the first and second substrates both located between the first and second polarizers.
- 2. The method of claim 1, further comprising the step of photo-imaging the diffusing material using ultraviolet radiation so as to form a diffusing layer.
- 3. The method of claim 2, further comprising the step of photo-imaging the diffusing material using ultraviolet radiation so as to form an array of discrete diffusing portions which make up the diffusing layer.
- 4. The method of claim 1, wherein the recited steps are performed in the order in which they are recited.
- 5. The method of claim 1, wherein the host material has a refractive index at least about 0.05 less than a refractive index of the particles, and wherein the particles are substantially transparent to all visible wavelengths of light and wherein the particles are substantially spherical in shape.
