1. A transflective liquid crystal display panel comprising:
a pixel array substrate comprising a first substrate, a plurality of pixel units, and a plurality of reflective layers, the pixel units and the reflective layers being disposed on the first substrate, wherein each of the pixel units has a transmissive region and a reflective region, and the reflective layers are disposed in the reflective region;
an opposite substrate disposed above the pixel array substrate and comprising a second substrate, a color filter layer, and a plurality of light scattering layers, the color filter layer and the light scattering layers being disposed on the second substrate and facing the pixel units, wherein a thickness of the color filter layer is greater than a thickness of each of the light scattering layers, a first bottom surface of the color filter layer is aligned to a second bottom surface of each of the light scattering layers, and the light scattering layers correspond to the reflective layers; and
a liquid crystal layer disposed between the pixel array substrate and the opposite substrate,
wherein each of the light scattering layers has a plurality of first regions and a plurality of second regions, the first regions and the second regions are alternately arranged, reflective particles are doped in each of the second regions, a distribution ratio of the reflective particles in each of the second regions is within a range from 5% to 50%, and the first regions are transparent regions without doped with a reflective particle.
