Abstract
A wearable type mobile terminal is provided which may be mounted on a user's head. The wearable type mobile terminal may include a prism disposed in front of a user, and positioned longitudinally, an optical source device that irradiates light to the prism in a direction that is inclined by a prescribed angle with respect to the longitudinal direction, and an asymmetric lens disposed between the prism and the optical source device such that light irradiated from the optical source device is collected toward the prism, and the asymmetric lens is formed such that an optical axis of an incident surface and an optical axis of an exit surface extend in different directions.
