Gate signal interconnection wires are formed at a corner portion of the substrate outside the display area to transmit gate electrical signals, and provided with gate signal interconnection lines and first and second gate signal interconnection pads connected to both ends of the gate signal interconnection lines. A gate insulating layer, and a protective layer are further formed on the substrate, and provided with first and second contact holes exposing the first and second gate signal interconnection pads. Gate and data signal transmission films are attached to the substrate, and provided with first and second gate signal leads and first and second gate signal wires.

Abstract: An ink-jet print head preventing thermal accumulation on a nozzle plate includes a substrate, a channel formed in the substrate to supply ink, a nozzle plate connected to the substrate and including a nozzle corresponding to the channel, a heat element formed in the nozzle plate to surround the nozzle, a thermal conduction layer formed on an upper side of the heat element formed between the thermal conduction layer and the heat element, and a thermal shunt spaced-apart from the heat element by a predetermined distance not to overlap the heat element in a direction parallel to the nozzle plate and connecting the thermal conduction layer to the substrate. Redundant heat generated from the heat element is not accumulated on a membrane of the nozzle plate but is rapidly absorbed into an inorganic thermal conduction layer formed in the membrane and is transferred to the bulk silicon substrate through a metallic thermal bridge, such as the thermal shunt.

Abstract: A bubble-jet type ink-jet printhead and manufacturing method thereof including a substrate integrally having an ink supply manifold, an ink chamber, and an ink channel; a nozzle plate having a nozzle on the substrate; a heater centered around the nozzle and an electrode for applying current to the heater on the nozzle plate; and an adiabatic layer on the heater for preventing heat generated by the heater from being conducted upward from the heater. Alternatively, a bubble-jet type ink-jet printhead may be formed on a silicon-on-insulator (SOI) wafer having a first substrate, an oxide layer, and a second substrate stacked thereon and include an adiabatic barrier on the second substrate. In the bubble-jet type ink-jet printhead and manufacturing method thereof, the adiabatic layer or the adiabatic barrier is provided to transmit most of the heat generated by the heater to ink under the heater, thereby increasing energy efficiency.
