Abstract
The present invention discloses a display panel comprises: a cholesteric liquid crystal cell configured to convert a light passing therethrough into a polarized light; a first light modulator, which is provided at a light output side of the cholesteric liquid crystal cell and directly contacts the cholesteric liquid crystal cell, configured to generate a phase retardation in the polarized light passing therethrough so as to modulate a polarization of the polarized light; a first linear polarizer provided at a side of the first light modulator opposite from the cholesteric liquid crystal cell and configured to selectively permit the polarized light modulated by the first light modulator to pass therethrough. The present invention also discloses a display apparatus.
