METHOD OF MAKING THIN FILM TRANSISTOR SUBSTRATE

摘要

PURPOSE: A method of making a thin film transistor substrate is provided to widen an angle of visual field by making an arrangement direction of liquid crystal molecules of each region formed differently. CONSTITUTION: The method of making a thin film transistor substrate is composed of forming a data wiring comprising a data line(51), a source electrode, a drain electrode and a data pad and forming a passivation insulating film(60) covering data lines(51) and a gate insulating film(20). A photoresist film is coated and exposed by a mask(100) so that a photoresist film pattern(80) is formed which is inclined toward an edge from a center of a pixel region. A passivation film pattern(80) is formed by etching the passivation insulating film(60) by use of the photoresist film pattern(80) as a mask.
