Patent ID: 8735901

Claim:
A display device comprising: a first substrate including a video signal line, a first electrode, a second electrode, a thin film transistor having a third electrode thereof connected to the video signal line and a fourth electrode thereof connected to the first electrode, a first inorganic insulation film formed above the fourth electrode, an organic insulation film formed above the first inorganic insulation film, a second substrate arranged to face the first substrate in an opposed manner, wherein the second electrode is formed above the organic insulation film, a second inorganic insulation film is formed above the second electrode and below the first electrode, the organic insulation film has a first contact hole, the first inorganic insulation film and the second inorganic insulation film form a second contact hole therein which penetrates both of the first inorganic insulation film and the second inorganic insulation film, the first electrode and the fourth electrode are connected to each other via the first contact hole and the second contact hole, the first inorganic insulation film has an upper surface which faces the second substrate, the second inorganic insulation film has a lower surface which faces the first substrate, at least a part of the lower surface faces the upper surface without the inorganic insulation therebetween.
