  • Publication number: 20150090336
    Abstract: The present invention provides an organic-inorganic composite light-emitting device including a luminescent layer emitting high-brightness light using low voltage, wherein the luminescent layer has a sandwich structure in which organic luminescent layers are formed on both sides of an inorganic thin film layer. The organic-inorganic composite light-emitting device configured as above is advantageous in that an inorganic thin film layer is inserted and formed between organic luminescent layers, and thus the injection of electrons that occurs when low voltage is applied stabilizes the structure of the luminescent layer, thereby emitting brighter light. Further, the organic-inorganic composite light-emitting device is effective in greatly improving the power efficiency of an organic light-emitting device by greatly increasing the luminance efficiency thereof.

  • Patent number: 7061015
    Abstract: A gate wire is formed on a substrate. Next, after forming a gate insulating film, a semiconductor layer and an ohmic contact layer subsequently are formed thereon. Next, a data wire is formed. Next, a passivation layer and an organic insulating film are deposited, and patterned to form contact holes for exposing the drain electrode, the gate pad and the data pad, respectively. Here, the organic insulating film around the contact holes is formed thinner than that in the other portions. Next, the organic insulating film around the contact holes is removed by an ashing process to expose the borderline of the passivation layer in the contact holes, thereby removing an under-cut. Then, a pixel electrode, an assistant gate pad and an assistant data pad respectively connected to the drain electrode, the gate pad and the data pad are formed.
