Abstract: Embodiments of the present disclosure provide a display panel, a method for manufacturing the same, and a display device, relating to the field of display technology. The display panel includes a first substrate, a second substrate, a liquid crystal layer disposed between the first substrate and the second substrate, and a light splitting structure disposed on a side of the first substrate facing away from the liquid crystal layer. The light splitting structure is configured to perform spectroscopic processing on light incident on the light splitting structure to obtain light of at least one color, and project the light of the at least one color onto a pixel of a corresponding color in the display panel.
