Abstract
A display panel includes: a liquid crystal cell; an optical layer configured to transmit part of light incident onto the optical layer whose polarization direction is parallel to a transmission axis of the optical layer, and reflect a remaining part of the light incident onto the optical layer; a first polarization structure configured to transmit part of light incident onto the first polarization structure whose polarization direction is parallel to a transmission axis of the first polarization structure, and absorb a remaining part of the light incident onto the first polarization structure; and a second polarization structure configured to transmit part of light incident onto the second polarization structure whose polarization direction is parallel to a transmission axis of the second polarization structure, and absorb a remaining part of the light incident onto the second polarization structure.
