Abstract
A display panel including: a first substrate and a second substrate disposed oppositely and a liquid crystal layer disposed between the first substrate and the second substrate; a material of the liquid crystal layer includes a cholesteric liquid crystal; the display panel further includes: a microstructure optical film layer located on a side of the second substrate facing away from the first substrate; incident light is incident from a side of the microstructure optical film layer, reflected by the cholesteric liquid crystal, and then emerged from the microstructure optical film layer; the microstructure optical film layer includes multiple wedge structures; at least part of the wedge structures have different angles and sizes, so that light emerged from side view angles with different emergent angles are adjusted to a center view angle.
