  • Publication number: 20120273787
    Abstract: In a thin film transistor array panel according to an exemplary embodiment of the present invention, a plasma process using a mixed gas including hydrogen gas and nitrogen gas with a ratio of a predetermined value is undertaken before depositing a passivation layer. In this manner, performance deterioration of the thin film transistor may be prevented and simultaneously, haze in a transparent electrode may be prevented. Alternatively, a first passivation layer is depsoited, then removed. A passivation layer is again re-deposited, such that little or no haze is present in the resulting passivation layer.

  • Patent number: 7696027
    Abstract: Disclosed is a method of fabricating a display substrate. A black matrix and a color filter layer are formed on a base substrate, and then a transparent electrode and a photoresist layer pattern are sequentially formed. The transparent electrode is patterned using the photoresist layer pattern as a mask to form a common electrode, and a spacer is formed using the photoresist layer pattern.
