Abstract
A display device includes: a substrate, on which pixel areas arranged substantially in a matrix form having pixel rows and pixel columns are defined; a thin film transistor disposed on the substrate; a pixel electrode disposed in the pixel areas and connected to the thin film transistor; common electrodes disposed on the pixel electrode and spaced apart from the pixel electrode, where a microcavity is defined between the pixel electrode and the common electrodes; a roof layer disposed on the common electrodes, where a liquid crystal injection hole is defined through the common electrodes and the roof layer and exposes the microcavity; a liquid crystal layer disposed in the microcavity; and an encapsulation layer disposed on the roof layer, where the encapsulation layer covers the liquid crystal injection hole and seals the microcavity, where the common electrodes in the pixel rows are connected to each other.
