Array substrate, liquid crystal display panel and manufacturing method for array substrate

A manufacturing method for an array substrate, comprising:

• sequentially forming a first light-shielding insulation layer and a first function layer on a substrate;
• adopting a first mask for exposing and developing the first light-shielding insulation layer and the first function layer at one time to respectively obtain a first light-shielding insulation pattern and a first function pattern, wherein, the first light-shielding insulation pattern includes a hollow region and a light-shielding region;
• the light-shielding region includes a first region and a second region;
• the first function pattern includes a hollow region and a function region;
• the hollow region of the first function pattern is corresponding to the hollow region and the first region of the first light-shielding insulation pattern, the function region of the first function pattern is corresponding to the second region of the first light-shielding insulation pattern;
• sequentially forming a second function layer and a third function layer above the first light-shielding insulation pattern and the first function pattern;
• and
• adopting a second mask for exposing and developing the second function layer and the third function layer at one time to respectively obtain a second function pattern and a third function pattern, wherein, each of the second function pattern and the third function pattern includes a hollow region and a function region;
• the function region of the second function pattern is corresponding to the function region of the third function pattern and the first region of the first light-shielding insulation pattern.
