Abstract:
1. A thin film transistor array substrate comprising: a gate line on a substrate; a gate insulating film on the gate line; a data line on the gate insulating film, the data line crossing the gate line to define a pixel region and the gate insulating film between the gate line and the data line, wherein at least one of the gate line and the data line includes a protrusion extending toward the pixel region and having a shape of a polygon including a rectangle or a circle, and the protrusion has a width ranging from about 30 μm to about 50 μm; a thin film transistor at a crossing the gate line and the data line; a pixel electrode at the pixel region, the pixel electrode connected to the thin film transistor; and a spacer within the protrusion dispensed by an ink-jet system, wherein the width of the protrusion is wider than a width of the spacer.
