Liquid crystal display device
A liquid crystal display device includes an active matrix substrate, a counter substrate, and a liquid crystal layer. The active matrix substrate includes a top gate type oxide semiconductor TFT a plurality of gate wiring lines a plurality of source and an interlayer insulating layer The counter substrate includes a plurality of columnar spacers provided on a second substrate. Each columnar spacer is disposed in an intersecting region where the gate wiring line and the source wiring line intersect. A front face of the active matrix substrate on the liquid crystal layer side includes a plurality of first ridges overlapping the plurality of gate wiring lines and a plurality of second ridges overlapping the plurality of source wiring lines.
