摘要： A manufacturing method of a color filter substrate includes Step S1: providing a base and forming an antireflection layer on the base; and Step S2: forming a color resist layer on the antireflection layer, in which the color resist layer is formed through a photolithographic process including operations of coating photoresist, exposure, and development. With the arrangement of the antireflection layer under the color resist layer, in a photolithographic process of the color resist layer, due to the arrangement of the antireflection layer under the photoresist, during exposure of the photoresist, the antireflection layer absorbs ultraviolet light incident into the antireflection layer and weakens, through destructive interference, reflection light emitting from the contact interface between the photoresist and the antireflection layer to eliminate the standing wave effect, the swing effect, and the notching effect of photolithography and improve key dimension consistency and pattern distinguishability of the color resist units.

摘要： Provided is a manufacturing method of an array substrate. When a first photomask is used to pattern a gate insulating layer to form a plurality of first conductive vias within the OLB area, by increasing a distance between two adjacent first via patterns to more than 10 μm, the effect of gray tone mask effect is reduced as a first conductive via is formed in the gate insulating layer Thus, a slope of the first photoresist via wall is relatively gentle, so that a slope of a via wall of the first conductive via is also relatively gentle, and as a passivation layer is formed thereafter, the passivation layer can be easily formed on the wall of the first conductive via without breaking. Then, a second metal layer in the first conductive via can be completely covered by the passivation layer to avoid oxidation.
