Active matrix substrate having spacers, liquid crystal display panel having spacers, liquid crystal display element, liquid crystal display device, and substrate for liquid crystal display panels

An active matrix substrate comprising

• a spacer on a substrate,
• wherein the spacer includes a base layer and a covering layer,
• the base layer being buried in the covering layer, and
• wherein the active matrix substrate includes a scanning line and a storage capacitor wiring on the substrate, the spacer is arranged on the scanning line and/or the storage capacitor wiring, and the spacer is positioned within a region where the scanning line and/or the storage capacitor wiring are/is positioned as viewed in plane.

An active matrix substrate comprising

• a spacer on a substrate,
• wherein the spacer includes a base layer and a covering layer,
• the base layer being buried in the covering layer,
• wherein the active matrix substrate further includes a second spacer on the substrate, the second spacer being shorter than the spacer;
