Title: ACTIVE MATRIX SUBSTRATE AND LIQUID CRYSTAL DISPLAY DEVICE
Abstract:
The present invention provides a highly precise active matrix substrate while suppressing occurrence of a pixel defect. This active matrix substrate is provided with: 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; 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 via a contact hole, wherein in plan view, a distance (dc) in the row direction from the drain electrode-side edge of the channel to the bottom surface of the contract hole is greater than or equal to 0.15 times a sub-pixel pitch (dp) in the row direction.
