Abstract
In a liquid crystal display device that uses a TFT, a contact hole is formed to connect an image signal line. An organic film is formed so as to cover the image signal line, and a common electrode, which is a transparent electrode, is formed on the organic film. An interlayer insulating film is formed on the common electrode. A through hole is formed in the interlayer insulating film, and the diameter of the through hole is greater than the diameter of the contact hole.
