Manufacturing method for liquid crystal display device

A display device comprising:

• a substrate;
• a first inorganic insulation film above the substrate, having a first hole;
• an organic insulation film above the first inorganic insulation film, having a second hole;
• a second inorganic insulation film above the organic insulating film, covering a sidewall of the second hole, and having a third hole;
• and
• an orientation film covering a first transparent conductive film, wherein
• the organic insulating film is provided between the first inorganic insulating film and the second inorganic insulating film,
• each of the first hole and the third hole is located in the second hole, the first hole and the third hole overlap each other in the second hole,
• the first inorganic insulation film contacts the second inorganic insulation film without the organic insulation film therebetween inside of the sidewall of the second hole,
• the first transparent conductive film is provided above the second inorganic insulating film,
• the second inorganic insulating film is provided between the first transparent insulating film and the organic insulating film,
• a metal portion is provided between the substrate and the first inorganic insulating film,
• the first transparent conductive film is in contact with the metal portion through the first hole and the third hole inside of the sidewall of the second hole, and
• the first transparent conductive film is provided between the second inorganic insulating film and the orientation film.
