Liquid crystal display and manufacturing method thereof

A manufacturing method of a liquid crystal display, comprising:

• forming a gate line and a common electrode line on a substrate;
• forming a semiconductor layer on the substrate;
• forming a data line crossing the gate line on the substrate;
• forming an insulating layer on the gate line, the common electrode line, the semiconductor layer and the data line;
• forming a pixel electrode on the insulating layer;
• forming a sacrificial layer on the pixel electrode;
• forming a contact hole exposing the common electrode line by patterning the insulating layer;
• forming a common electrode formed on the sacrificial layer and connected to the common electrode line through the contact hole;
• forming a support member on the common electrode;
• forming a microcavity including a liquid crystal injection hole by removing the sacrificial layer;
• injecting a liquid crystal material into the microcavity;
• and
• forming a capping layer on the support member so as to cover the liquid crystal injection hole.
