Abstract
The present invention provides a technique which can make an image quality on a screen of a TFT liquid crystal display device uniform. A liquid crystal display device includes a TFT substrate on which TFT circuits are arranged in an array, a counter substrate which is arranged to face a surface of the TFT substrate on which the TFTs are formed, and a liquid crystal material which is filled between the TFT substrate and the counter substrate, wherein in the TFT substrate, assuming a film thickness and a width of a conductive film of the gate electrode lines in a first region thereof as GLDand GLWrespectively, and a film thickness and a width of a conductive film of the gate electrode lines in a second region thereof which differs from the first region as GLDand GLWrespectively, when the relationship GLD<GLDis established, the relationship GLW>GLWis established.
