Liquid crystal display device

摘要

In a liquid crystal display device that uses a top gate TFT, a contact hole (130) is formed to connect to an image signal line (40). An inorganic passivation film (108) and an organic passivation film (109) are formed in this order so as to cover the TFT, on which a common electrode is formed. Then, an interlayer insulating film (106) is formed on the common electrode. A through hole (140) for gas release is formed in the interlayer insulating film (106). The diameter of the through hole (140) is greater than the diameter of the contact hole (130), so as to be able to easily release gas from the organic passivation film (109), and to prevent the interlayer insulating film (106) from peeling off.
