Abstract
A display device includes a plurality of pixel areas and a thin film transistor disposed on a substrate. A first light blocking member is disposed on the thin film transistor, and a contact hole is disposed in the first light blocking member to expose a portion of the thin film transistor. A pixel electrode is disposed on the first light blocking member, and connected with the thin film transistor through the contact hole. A second light blocking member is disposed on the pixel electrode overlapping with the contact hole. A roof layer is disposed spaced apart from the pixel electrode with a microcavity interposed therebetween. An injection hole is disposed below the roof layer to expose a portion of the microcavity, and a liquid crystal layer is disposed in the microcavity. An encapsulation layer is disposed on the roof layer covering the injection hole so as to seal the microcavity.
