Abstract
There is provided a high-definition active matrix substrate while suppressing an occurrence of pixel defects. The active matrix substrate includes a first semiconductor film corresponding to one of two sub-pixels adjacent to each other in a row direction, a second semiconductor film corresponding to the other of two sub-pixels, a transistor using part of the first semiconductor film as a channel in the row direction, and a pixel electrode connected to a drain electrode of the transistor through a contact hole. In a plan view, a distance (dc) in the row direction from a drain electrode-side edge of the channel to a bottom surface of the contact hole is 0.15 or more times a sub-pixel pitch (dp) in the row direction.
