Patent ID: 7961263

Claim:
A liquid crystal display, comprising: a substrate; a gate line formed on the substrate; a gate pad electrically connected to the gate line; a common electrode formed on the substrate; a gate insulating layer covering the gate line, the gate pad and the common electrode and exposing at least a portion on the gate pad; a semiconductor layer formed on the gate insulating layer; source and drain electrodes formed on the semiconductor layer; a data line electrically connected to the source electrode; a data pad electrically connected to the data line; a pixel electrode electrically connected to the drain electrode and having a thickness smaller than that of the data line; and a passivation layer formed on the pixel electrode and the common electrode and having a surface substantially flat enough for uniform rubbing and a larger thickness than a thickness of the pixel electrode, and having a lower surface contacting the pixel electrode, the common electrode, wherein the thickness of the pixel electrode substantially contributes to the flatness of the surface of the passivation layer and is less than or equal to about 500 angstroms, and wherein the pixel electrode and the data line include at least one same material as each other.
