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.
