Abstract
Disclosed is a method of preparing a thin film transistor substrate, a thin film transistor substrate, and a display apparatus. The method includes forming a conductive material layer, forming a hydrophobic insulation layer on the conductive material layer, forming a photoresist layer on the hydrophobic insulation layer, patterning the photoresist layer to form a photoresist pattern, removing a segment in the hydrophobic insulation layer that is not covered by the photoresist pattern to form a hydrophobic insulation pattern, and removing a segment in the conductive material layer that is not covered by the hydrophobic insulation pattern to form a conductive pattern.
