A TFT substrate is provided to connect a pixel electrode with a drain electrode stably according as a profile of a contact hole is gently formed at a summit part. A TFT(Thin Film Transistor) substrate comprises a line(21,22,23), an insulating layer and a transparent electrode layer(61,62,63). The insulating layer is formed on the line. In the insulating layer, contact holes(71,72,73) for exposing the line are formed. The transparent electrode layer is electrically connected with the line through the contact hole. The contact holes face each other and have two sides where the angle of the sides is from 15 to 45 degrees. |
