Member to be recognized for alignment; head unit and electronic device provided therewith; method of manufacturing LCD, organic EL device, electron emission device, PDP device, electrophoretic display device, color filter, and organic EL; method of forming spacer, metallic wire, lens, resist, and light diffusion member, each of said methods using said head unit

Abstract

A method of manufacturing a device includes introducing each color of material into a plurality of liquid droplet ejection heads and scanning the plurality of liquid droplet ejection heads relative to a substrate through a head unit to selectively eject the material, wherein the head unit includes a carriage with two members recognized for alignment, each member being disposed in an object set in position and having formed therein a mark for image-wise recognition, each member comprising a member main body formed substantially in a columnar shape and having a mirror-finished front end surface, wherein the marks are formed into a depressed shape in a substantially central part of the front end surface of each member main body and the marks are disposed at a distance from each other, and the plurality of liquid droplet ejection heads mounted on the carriage.
