Display panel and manufacturing method for display panel

A manufacturing method for a display panel comprising the following steps:

• a first substrate manufacturing step, dispensing a sealant layer on a lower surface of a first substrate;
• a second substrate manufacturing step, coating a liquid crystal layer on an upper surface of a second substrate;
• an assembling step, correspondingly assembling and laminating the first substrate and the second substrate;
• and
• a first alignment film layer manufacturing step, performing heat and light treatment to the first substrate to form a first alignment film layer;
• wherein the first substrate manufacturing step comprises the following steps:
• a first underlying layer disposing step, disposing a first underlying layer;
• a common electrode layer manufacturing step, manufacturing a common electrode layer on an upper surface of the first underlying layer;
• and
• a first liquid crystal alignment monomer layer coating step, coating a liquid crystal alignment monomer material on an upper surface of the common electrode layer to form a first liquid crystal alignment monomer layer;
• wherein performing heat and light treatment to the first substrate will make a link reaction occur between the common electrode layer and the first liquid crystal alignment monomer layer and form the first alignment film layer.
