A display device and a method of manufacturing the display device improve reliability by preventing contact between a color filter, a light blocking member and a liquid crystal layer. The display device includes: a substrate including pixel areas; a thin film transistor formed on the substrate; a pixel electrode connected to the thin film transistor and formed in the pixel areas; a roof layer formed on the pixel electrode; microcavities interposed between the pixel electrode and the roof layer; an injection hole formed in the roof layer, the injection hole configured to expose at least a portion of the microcavities; a liquid crystal layer filled in at least one of the microcavities; an encapsulation layer formed on the roof layer, the encapsulation layer configured to cover the injection hole and to seal the microcavities; and an organic layer formed on the encapsulation layer.
