The invention discloses a display panel, a preparation method of the display panel, and a
display device, and belongs to the technical field of display. The preparation method of the display panel comprises the steps of binding a first substrate and a second substrate in a contraposition manner, arranging
liquid crystal comprising a photosensitive curing
liquid crystal monomer between the first substrate and the second substrate in a clamping manner, irradiating the whole substrate by UV (
ultraviolet) polarized light, and completing
liquid crystal orientation and frame seal glue precuring. The method simplifies a preparation technology process of the display panel, lowers the cost, and improves the productive capacity. When the whole substrate is irradiated by the UV polarized light, the photosensitive curing liquid
crystal monomer forms a
polymer grid on the surface of an orientation layer under
irradiation of the UV polarized light, so that a surface anchorage force of the orientation layer is increased, and a residual image and a residual shadow of the display panel are improved. The embodiment of the invention further provides the display panel prepared by the preparation method and the
display device comprising the display panel.
