Abstract
Provided is a display device capable of preventing a liquid crystal from being left outside a microcavity. The display device includes: a substrate; a pixel electrode formed on the substrate; a roof layer formed on the pixel electrode so as to be spaced apart from the pixel electrode with a plurality of microcavities therebetween; a light blocking member positioned between two microcavities of the plurality of microcavities, overlapping with a first edge of one microcavity of the two microcavities, and not overlapping with a second edge of the other microcavity; an injection hole exposing a part of the microcavity; a liquid crystal layer filling the microcavity; and an encapsulation layer formed on the roof layer so as to cover the injection hole to seal the microcavity.
