A liquid crystal display apparatus includes a first liquid crystal layer having first liquid crystal exhibiting a cholesteric phase at a room temperature, and being tuned to selectively reflect light of a wavelength lambda1 within a visible wavelength range; and a second liquid crystal layer disposed on the first liquid crystal layer, having second liquid crystal exhibiting a cholesteric phase at the room temperature, and being tuned to selectively reflect light of a wavelength lambda2 within the visible wavelength range, wherein a difference between the selective reflection wavelengths lambda1 and lambda2 is in a range from 100 nm to 150 nm.
