Abstract
The invention provides a PDLC display panel, manufacturing method thereof, and an LCD. The PDLC display panel comprises a PDLC layer, which comprising a plurality of red sub-pixel portions, green sub-pixel portions, and blue sub-pixel portions. The red, green and blue sub-pixel portion is a PDLC film having red, green and blue dye, respectively. The light passing through the red, green, and blue sub-pixel portions of the PDLC layer displays red, green and blue colors respectively. The PDLC display panel is simple in structure, on the premise to achieve color display, eliminating the upper and lower polarizers, polyimide (PI) alignment layer, CF layer and the black matrix, to achieve high light penetration rate and low manufacturing costs, as well as high backlight utilization with the use of quantum dot layer in the CF substrate.
