A display device includes: a substrate which includes a plurality of pixel areas disposed in a matrix configuration; a pixel electrode positioned in each of the pixel areas; a roof layer positioned on the pixel electrode and spaced apart from the pixel electrode with a microcavity therebetween; injection holes respectively positioned at two edges of the microcavity; a support positioned at one edge of the microcavity and adjacent to one of the injection holes; an alignment layer positioned on an inner surface of the microcavity; and a liquid crystal layer positioned in the microcavity. The support is disposed at each of opposite edges of two microcavities which are adjacent to each other in a column direction.
