ACTIVE MATRIX SUBSTRATE, PRODUCTION METHOD FOR SAME, AND LIQUID CRYSTAL DISPLAY PANEL

摘要

Disclosed is an active matrix substrate (30a) comprising: a plurality of pixels disposed in a matrix; a plurality of switching elements (5a) each disposed in each pixel; a first protective insulating film (20a) disposed on top of each switching element (5a): a transparent conductive layer (21b) disposed on top of the first protective insulating film (20a); a second protective insulating film (22a) disposed on top of the transparent conductive layer (21b); and a plurality of pixel electrodes (23a) disposed on top of the second protective insulating film (22a) in a matrix and each connected to each switching element (5a). A groove (G) is formed in the second protective insulating film (22a) such that the first protective insulating film (20a) is exposed along the circumference of each pixel electrode (23a) and the transparent conductive layer (21b) is disposed so as to be exposed along the groove in the second protective insulating film (22a) from a side wall (W) of the groove (G) in a state recessed from the side wall (W) of the groove (G).
