Array substrate and manufacture method thereof, liquid crystal display panel

A manufacture method of an array substrate, comprising the following steps:

• forming a common line on the substrate;
• forming a separation layer that covers the common line on the substrate;
• forming a first via hole in the separation layer;
• forming a gate line layer on the separation layer;
• forming a first insulation layer on the gate line layer;
• forming a data line layer on the first insulation layer;
• forming a second insulation layer on the data line layer;
• forming a first long via hole communicated with the first via hole in the second insulation layer;
• forming a first transparent electrode on the second insulation layer, the first transparent electrode penetrates the first long via hole to connect, through the first via hole, to the common line;
• forming a third insulation layer on the first transparent electrode;
• forming a second long via hole communicated with the data line layer in the third insulation layer;
• forming a second transparent electrode on the third insulation layer, the second transparent electrode penetrates the second long via hole to connect with the data line layer;
• and
• wherein the step of forming a gate line layer on the separation layer comprises forming a conductive block that penetrates the first via to connect with the common line, such that the first transparent electrode that penetrates the first long via hole is connected to the conductive block that penetrates the first via hole to connect with the common line.
