    Abstract: The present invention discloses a display panel comprising: a cholesteric liquid crystal cell in which a cholesteric liquid crystal exhibiting a planar texture state distribution is filled; a first light modulator provided at a light output side of the cholesteric liquid crystal cell, configured to generate a phase retardation in a polarized light passing therethrough so as to modulate a polarization of the polarized light, and comprising a liquid crystal layer and a drive electrode for driving liquid crystal molecules in the liquid crystal layer to deflect so as to regulate an amount of the phase retardation of the polarized light passing through the liquid crystal layer; and 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.

    Abstract: A display panel provided according to the present disclosure may include an optical component and two Guest Host liquid crystal cells located at two opposite sides of the optical component. The optical component is used for reflecting light with a specific wavelength and transmitting other light. The Guest Host liquid crystal cells each include a plurality of pixel units each having two operation states of transmitting natural light and linearly polarized light. When the pixel units transmit the linearly polarized light, the light reflected by the optical component cannot pass through the pixel units, thereby achieving a dark state display.

    Abstract: A display panel is provided. The display panel includes a base substrate; a separation structure on the base substrate; a recess extending into the separation structure; a color filter on a side of the separation structure away from the base substrate; and a lens layer including a plurality of lenses and on a side of the color filter away from the base substrate. An orthographic projection of a respective lens on the base substrate partially overlaps with an orthographic projection of the separation structure on the base substrate. The recess includes a first recess portion and a second recess portion connected with each other. In plan view of the display panel, a gap between two adjacent lenses of the plurality of subpixels is in a region at least partially overlapping with a region having both the first recess portion and the second recess portion.
