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.

Abstract: A display device and a method of manufacturing the display device are provided. Moisture may be prevented from penetrating into the display device. The display device includes a substrate including a pixel area. A thin film transistor is formed on the substrate. A pixel electrode is connected to the thin film transistor and formed in the pixel area. A roof layer is formed on the pixel electrode. The roof layer is separated from the pixel electrode via a microcavity. A liquid crystal layer fills the microcavity. A liquid crystal injection hole is formed in the roof layer and exposes a portion of the microcavity. An encapsulation layer is formed on the roof layer. The encapsulation layer covers the liquid crystal injection hole and seals the microcavity for the pixel area. The encapsulation layer includes a multilayer structure.
