Abstract: Embodiments relate to a liquid crystal display and a manufacturing method thereof, and more particularly, to a liquid crystal display including an alignment layer pattern and a manufacturing method thereof. The liquid crystal display includes a lower panel including a first alignment layer and a signal line. An upper panel faces the lower panel and uncovers an end portion of the signal line of the lower panel. A sealant is positioned between the lower panel and the upper panel and couples the lower panel and the upper panel with each other. The first alignment layer includes a coated region positioned between a first removed region overlapping the end portion of the signal line and a second removed region overlapping the sealant. The first alignment layer does not exist in the first removed region and the second removed region.
