Abstract
Methods of manufacturing a liquid crystal display ('LCD'); specifically, a multi-color LCD, e.g., a red-green-blue ('RGB') LCD. The methods include the steps of: (1) depositing a twist agent on a first substrate, the twist agent becoming an in situ twist agent, (2) bringing a second substrate into proximity with the first substrate to form at least one interstitial region between the second and first substrates, (3) introducing liquid crystal ('LC') having an initial pitch into the at least one interstitial region proximate the in situ twist agent and (4) stimulating the LC and the in situ twist agent to cause the LC and the in situ twist agent to mix in situ, the in situ twist agent changing the initial pitch of the LC.
