Beschreibung
Zusammenfassung:	A display substrate includes a base substrate and a plurality of insulating layers disposed on a surface of the base substrate. A groove is defined in the insulating layers in a non-display area of the display substrate. An end portion of an alignment layer is disposed in the groove. The groove is capable of controlling a flow of a liquid alignment material to prevent the liquid alignment material from overflowing to an edge of the base substrate. The groove is formed simultaneously in a process of forming contact holes in a display area of the display substrate. Accordingly, a structure corresponding to the end portion of the alignment layer to control the flow of the liquid alignment material is formed without increasing the number of masks.
