Display panel and manufacturing method thereof

A display panel comprising a plurality of pixels, each of which comprises a transmission region and a reflection region, and a first polarizer, a first base substrate, a first alignment layer, a liquid crystal layer, a second alignment layer, a second base substrate, and a second polarizer that are disposed in turn;

• wherein a reflection layer is provided between the second alignment layer and the second polarizer in the reflection regions;
• the liquid crystal layer in the reflection region comprises nematic liquid crystal and a polymer network;
• the liquid crystal layer in the transmission region comprises a liquid crystal mixture comprising the nematic liquid crystal and polymerizable monomers;
• the polymer network in the reflection region is formed by polymerizing the polymerizable monomers in the liquid crystal mixture;
• and
• in case of no electric field, an alignment direction of the nematic liquid crystal in the reflection region is different from that of the first alignment layer, and an alignment direction of the nematic liquid crystal in the transmission region is same as that of the first alignment layer;
• wherein polarization transmission directions of the first polarizer and the second polarizer are perpendicular to each other;
• an orientation of the first alignment layer and an orientation of the second alignment layer are parallel or anti-parallel to each other;
• the orientation of the first alignment layer is perpendicular to the polarization transmission direction of the first polarizer;
• and
• in case of no electric field, the liquid crystal layer in the reflection region is capable of deflecting, by 90 degrees, a polarization direction of linearly polarized light incident in a direction from the first base substrate and reflected by the reflection layer;
• a thickness d of the liquid crystal layer satisfies a formula:
• 2nd=λ(2k+3/2), where n is a specific birefringence of the nematic liquid crystal, k is a unit-less integer greater than or equal to 0, and λ is a wavelength, of visible light, a unit of λ is nm, and a unit of d is μm.
