Abstract
An active device array substrate includes: a substrate, a switch device, an inter-layer dielectric layer, an insulation bump, a conductive layer, and a pixel electrode. The switch device is located on the substrate. The inter-layer dielectric layer is located on the switch device, and the inter-layer dielectric layer has at least one opening, where the opening does not cover at least one part of a drain electrode of the switch device. The insulation bump covers at least partially the opening. The conductive layer is located on a top surface and a side wall of the insulation bump, and is electrically connected to the drain electrode of the switch device through the opening. The pixel electrode is electrically connected to the conductive layer.
