Abstract
A method to manufacture a display device, includes: forming, on a substrate of the display device, a sacrificial layer including a material, the material including at least one of amorphous carbon, a metal, and an inorganic material; forming a layer covering the sacrificial layer; forming an injection hole exposing the sacrificial layer; removing, via the injection hole, the sacrificial layer to form a microcavity; and disposing liquid crystal in the microcavity.
Claims13
A method, comprising:
- forming, on a substrate of a display device, a sacrificial layer comprising a material, the material comprising at least one of amorphous carbon, a metal, and an inorganic material;
- forming an electrode covering the sacrificial layer;
- forming a lower insulating layer covering the electrode;
- forming, after forming the lower insulating layer, a layer covering the sacrificial layer;
- forming an injection hole exposing the sacrificial layer;
- removing, via the injection hole, the sacrificial layer to form a microcavity;
- disposing liquid crystal in the microcavity;
- and
- forming, after forming the layer covering the sacrificial layer, an upper insulating layer covering both the layer covering the sacrificial layer and an exposed portion of the lower insulating layer formed in the region associated with the injection hole,
- wherein the layer covering the sacrificial layer is disposed outside a region associated with the injection hole.
