摘要： A liquid crystal display device has pixels in a TFT substrate, each of the pixels has a TFT. An organic insulting film 108 is formed to cover the TFT. A first electrode 109 and a second electrode 111 are formed above the organic insulting film 108 with an inorganic insulating film 110 placed between the first electrode 109 and the second electrode 111. An alignment film is formed on the first electrode 109 and the second electrode 111. The second electrode 111 connects with the TFT through a contact hole formed in the organic insulating film 108. A cross section of the organic insulating film 108 that includes the contact hole and is parallel to the second direction has a convex section and a concave section 70 at a bank located near the contact hole, the convex section being located closer to the contact hole than the concave section 70.
