A method of manufacturing a display device, the method comprising:
- irradiating a laser light onto a substrate to form a hole line in the substrate;
- forming an etch stopper layer on the substrate to overlap the hole line, the etch stopper layer including amorphous carbon;
- forming a buffer layer on the etch stopper layer;
- etching the substrate to form a first hole corresponding to the hole line;
- forming a second hole corresponding to the first hole in the etch stopper layer;
- forming a third hole corresponding to the second hole in the buffer layer;
- and
- disposing a display element layer including a light emitting element that emits light in response to an electrical signal provided to the light emitting element.
