Anisotropic retardation layers for display devices |
| abstract |
A composition (I) with includes the following compounds: wherein R1, which may be the same or different, is a hydrophilic group; R2, which may be the same or different, is selected from the group consisting of electron donating groups, electron withdrawing groups, and electron neutral groups; R3 is a substituted or unsubstituted, positively charged heteroaromatic ring linked to the triazine backbone through a nitrogen atom in the R3 ring; and X- is a counterion. If R3 is an unsubstituted pyridine, the counterion X- may be selected from any counterion other than Cl- and OH-. Otherwise, the counterion X- may be selected from any counterion. The compound may be applied to a substrate to form a birefringent optical retardation device. The retardation device may be used in display devices such as computers and the like to correct the phase and polarization states of the display's emitted light and improve image quality at viewing angles away from the normal. |
