Abstract
A liquid crystal display comprises a substrate comprising a thin film transistor area and a pixel area, a gate line formed on the substrate, a gate dielectric layer formed on the gate line and the substrate, an active layer formed on the gate dielectric layer, a doped layer formed on the active layer, a metal layer formed on the doped layer, a passivation layer overlaying the thin film transistor area and the pixel area, and a pixel electrode layer formed on the passivation layer. The gate line, the gate dielectric layer, the active layer, the doped layer and the metal layer in the thin film transistor area constitute a thin film transistor. The metal layer in the pixel area comprises a contact portion and a metal portion which is thick enough to partially transmit and partially reflect incident light to form a transflective region.
