Abstract: A liquid ejection apparatus has an ejecting portion that ejects a droplet of a liquid containing a functional material onto an object. The ejecting portion includes a transmittable member. A laser radiating portion radiates a laser beam onto the transmittable member. The transmittable member divides the laser beam into a first laser beam and a second laser beam. The first laser beam transmits through the transmittable member in such a manner that a radiating position of the first laser beam coincides with a droplet receiving position at which the droplet is received by the object or a position in the vicinity of the droplet receiving position. The second laser beam reaches a position defined on the object different from the radiating position of the first laser beam. This structure ensures accurate laser radiation onto the droplet and efficient drying and baking of the droplet.
