Abstract
An LTPS array substrate includes: a substrate on which a gate is disposed. An insulating layer and a polycrystalline silicon layer are disposed in sequence on the substrate and the gate. The insulating layer has an upper surface that is a plane. A source and a drain are disposed on the polycrystalline silicon layer and a pixel electrode is disposed on the insulating layer and a part of the drain. A plain passivation layer is disposed on the source and drain and includes a contact via formed therein at a location outside the polycrystalline silicon layer to expose a surface of one of the gate, the source, and the drain. A transparent electrode layer is disposed on the plain passivation layer to be electrically connected to the surface of the one of the gate, the source, and the drain that is exposed through the contact via.
