Claim:
1. A display device, comprising: a substrate including a plurality of pixel areas which are disposed in a matrix form including a plurality of pixel rows and a plurality of pixel columns; a thin film transistor formed on the substrate; a pixel electrode connected to the thin film transistor and formed in the pixel area; a common electrode formed on the pixel electrode to be spaced apart from the pixel electrode with a microcavity therebetween; a liquid crystal layer filling the microcavity between the pixel electrode and the common electrode; a roof layer formed on the common electrode; a liquid crystal injection hole formed in the common electrode and the roof layer to expose a part of the microcavity; and an overcoat formed on the roof layer so as to cover the liquid crystal injection hole to seal the microcavity, wherein a cross section of the microcavity has a reverse-tapered trapezoidal shape in which an upper width is larger than a lower width, and wherein a horizontal width of the microcavity is gradually decreased according to an increase in a distance from a center of a display panel.
