Abstract
A liquid crystal display device, comprising: a liquid crystal layer comprising a cholesteric liquid crystal and a self-organizing type gelling agent, and a manufacturing method thereof, comprising: spreading a cholesteric liquid crystal containing a gelling agent in a heated state over at least one of substrates to form a liquid crystal layer, or a manufacturing method thereof, comprising: spreading a cholesteric liquid crystal that contains a gelling agent and exhibits flowability at room temperature over at least one of substrates to form a liquid crystal layer.
