1. A display panel comprising:
a color filter (CF) substrate comprising a plurality of first support structures;
a thin film transistor (TFT) substrate comprising a plurality of second support structures, each of the plurality of first support structures supporting the TFT substrate, and each of the plurality of second support structures supporting the CF substrate, a receiving space is defined between the CF substrate and the TFT substrate; and
a liquid crystal layer in the receiving space, the TFT substrate being configured to apply a plurality of driving signals to the liquid crystal layer to modulate backlight received by the liquid crystal layer, and the CF substrate being configured to generate image light for displaying images by filtering the modulated backlight;
wherein the CF substrate further comprises a filter layer comprising a black matrix and a plurality of filters, the black matrix is in a grid shape and defines a plurality of filter areas, each of the plurality of filters is in a corresponding one of the plurality of filter areas; the plurality of filters comprises filters that transmit green light and along a direction perpendicular to a thickness direction of the display panel, the plurality of second support structures is closer to the filters that transmit green light than the plurality of first support structures.
