  • 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.

    Abstract: Contamination is blocked from material of a color filter layer provided on a thin-film transistors (TFT) supporting substrate by sealing over the color filter layer with an inorganic insulating layer. During mass production manufacture, a plasma surface cleaning step is employed after the color filter layer is deposited but before the inorganic insulating layer is deposited. A low temperature CVD process is used to deposit the inorganic insulating layer with a substantially uniform thickness conformably over the color filter layer including conformably into openings provided through the color filter layer.
