Abstract
A liquid crystal display includes a substrate; a transistor over the substrate, the transistor having a gate, a source, and a drain; a passivation layer over the transistor; a light shielding layer over a portion of the passivation layer over the transistor; a planarization layer over the light shielding layer and the passivation layer, the planarization layer having a contact hole over one of the source and the drain; a pixel electrode over the planarization layer, the pixel electrode being connected to the one of the source and the drain through the contact hole; and an alignment layer over the pixel electrode.
