The present invention discloses a display panel and a manufacturing method thereof. The display panel includes a plurality of liquid crystal cells, each of the plurality of liquid crystal cells includes cholesteric liquid crystals, and a chiral rotation direction of the cholesteric liquid crystals in one of the plurality of liquid crystal cells is opposite to a chiral rotation direction of the cholesteric liquid crystals in its adjacent ones of the liquid crystal cells, so that the cholesteric liquid crystals films with different rotation directions are designed between adjacent pixels, and one of any two adjacent pixels allows light to pass through, and another one of the two adjacent pixels blocks the light from passing through and reflects the light back into the display device, thereby achieving an object of reducing crosstalk.

Disclosed herein are techniques for displaying images on multiple image planes in a near-eye display system. A switchable optical device includes a first polarizer configurable to polarize incident light into light of a first circular polarization state, and a second polarizer configurable to transmit light of a second circular polarization state and reflect light of the first circular polarization state into light of the first circular polarization state. The switchable optical device also includes a partial reflector positioned between the first polarizer and the second polarizer. The partial reflector is configured to transmit light from the first polarizer and reflect light from the second polarizer, where the reflected light and the light from the second polarizer have different polarization states. At least one of the first polarizer or the second polarizer includes a cholesteric liquid crystal (CLC) circular polarizer that is switchable by a voltage signal.

Provided is an organic EL display device in which blue brightness is improved, and an antireflection function in an oblique direction is enhanced. The problem is solved by ensuring that a polarizer, a phase difference layer, a circularly polarized light separating layer, and a light emitting element are provided from a viewing side, an in-plane retardation Re(550) of the phase difference layer is set to 100 to 160 nm, the circularly polarized light separating layer is a cholesteric liquid crystal layer having a selective reflection center wavelength in a range of 425 to 475 nm, and a sum of retardations Rth(550) in a thickness direction of members arranged between the polarizer and the light emitting element is set to 50 to 50 nm.

Thus, in the display device according to the present disclosure, the overall thickness may be decreased without degrading the quality of the image realized by the display module.
