Patent ID: 7385663

Claim:
A liquid crystal display, comprising: a first substrate; a gate line assembly formed on the first substrate, the gate line assembly comprising a gate line and a gate electrode; a gate insulating layer covering the gate line assembly; a semiconductor pattern formed on the gate insulating layer over the gate electrode; a data line assembly formed on the gate insulating layer and the semiconductor pattern, the data line assembly comprising a source electrode, a drain electrode and a data line, the data line crossing the gate line; a protective layer covering the gate insulating layer, the semiconductor pattern, the data line, the source electrode and the drain electrode over the gate line and the gate electrode except a portion of the drain electrode; a protrusion formed at the first substrate, the protrusion comprising an under-layer formed with the same material as the gate insulating layer, and an over-layer formed with the same material as the protective layer; a pixel electrode connected to the drain electrode and covering the protrusion; a second substrate facing the first substrate; and a common electrode formed at the second substrate.
