Thin film transistor display panel and manufacturing method thereof

摘要

The present invention relates to a thin film transistor array panel that includes an organic layer formed on a data line and a drain electrode disposed on a color filter. A thickness of a portion of the organic layer around a contact hole exposing a portion of the drain electrode is similar to a thickness of a portion of the organic layer around a contact hole exposing a portion of the data line. Having approximately the same thickness can prevent non-uniform etching of the organic layer around contact holes and deterioration of the thin film transistor array panel.
