A display device and a manufacturing method thereof are provided. This substantiates a method of designing a reflective surface of a reflector in a vehicle lamp with improved controllability of a light distribution pattern and with improved efficiency of a designing work. In this aggregated state, contrast media assume the role of multivalent antigens and can successfully compete with any other antigens involved in antibody-antigen reactions that lead to anaphylaxis. The outlet manifold defines an aperture oriented such that exhaust gas passes through the aperture and out of the outlet manifold in a third direction that is substantially opposite the first direction.
