[Object] To provide a display device and a mobile terminal device that can be reduced in size and weight by simplifying a configuration. [Constitution] Laser lights from a projector module 31 enter a main reflective region 32M and a sub reflective region 32S for scanning by a movable mirror 330. The laser lights reflective on the main reflective region 32M of a first reflective mirror 32 are used to scan a back side of a main screen 34 through a second reflective mirror 33. This scanning allows a main image to be displayed on a front side of the main screen 34. Meanwhile, laser lights reflected on the sub reflective region 32S of the second reflective mirror 32 are used to scan a back side of a sub screen 35. This scanning allows a sub image to be displayed on a front side of the sub screen 35.
