  • Patent number: 7605875
    Abstract: Disclosed is a simplified manufacturing method for liquid crystal displays. A gate wire including a gate line, a gate pad and a gate electrode is formed on an insulating substrate. Next, a gate insulating layer covering the gate wire, a semiconductor layer, an ohmic contact layer, and a data conductive layer are sequentially deposited, and a photoresist pattern is formed on the data conductive layer. Following this step, the data conductive layer, using the photoresist pattern as an etch mask, is etched to form a data wire including a data line, a source electrode, a drain electrode, and a data pad. Next, the photoresist pattern is reflowed to cover the portion between the source electrode and the drain electrode, and a portion of the ohmic contact layer adjacent to a periphery of the data wire. Subsequently, portions of the ohmic contact layer and the semiconductor layer, which are not covered by the photoresist pattern, are etched, and the photoresist pattern is removed.
