The embodiment of the invention provides a display panel, a preparation method thereof and a display device, and the display panel comprises a gate insulating layer which is provided with a groove; at least part of the metal wire is arranged in the groove; the color resistance layer is arranged on the side, away from the gate insulation layer, of the metal wire, the color resistance layer comprises at least two color resistors, every two adjacent color resistors are arranged in a stacked mode in the area corresponding to the metal wire so as to form an ox horn area, and the area, arranged in a single-layer mode, of each color resistor is a flat area; the alignment film is arranged on the side, away from the metal wires, of the color resistance layer; the liquid crystal layer is arranged on the side, away from the metal wires, of the alignment film. Wherein the ox horn area corresponds to the groove. The grooves corresponding to the ox horn areas are formed in the gate insulation layer, and the grooves can contain at least part of the metal wires, so that the height of the alignment film corresponding to the ox horn areas can be reduced, diffusion of the alignment film is uniform, liquid crystal alignment is normal, and the uniformity of picture display of the display panel is improved.
Description
technical field [0001] The present application belongs to the technical field of display devices, and in particular relates to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In recent years, the LCD (Liquid Crystal Display, liquid crystal display) industry has developed rapidly, and many new technologies have been developed. Among them, the COA (Color Filter on Array, color filter attached to the array substrate) technology, which is to make the color resistance originally made on the CF (Color Filter, color filter) side on the TFT (Thin Film Transistor, thin film transistor) side, which can reduce the parasitic capacitance of the pixel and increase the aperture ratio of the pixel. [0003] In the prior art, the design of the pixel is to deposit a gate insulating layer under the signal line, and directly cover two kinds of color resistance after depositing a passivation layer above the signal line, one color resistance i...
