A liquid crystal display panel, a manufacturing method therefor, and a display device. By making an auxiliary spacer (04) in a liquid crystal display panel out of a piezoelectric material, when the liquid crystal display panel is under pressure, the auxiliary spacer (04) is compressed and generates a piezoelectric signal; a pressure sensing electrode (05) at a corresponding position is in contact with the auxiliary spacer (04), and the pressure sending electrode (05) obtains the piezoelectric signal, so as to achieve a pressure-sensing touch function of the liquid crystal display panel. Because the auxiliary spacer (04) in the liquid crystal display panel is made of the piezoelectric material, the auxiliary spacer (04) can also be used as a pressure-sensing touch layer, so that there is no need to make a touch layer separately, and therefore, the thickness of the liquid crystal display panel can be reduced and the manufacturing process thereof can be simplified. Moreover, the auxiliary spacer (04) generates charges only under pressure and is in a floating state under no pressure, and therefore, power consumption of the liquid crystal display panel can be reduced.
