Abstract
A display apparatus is provided. The display apparatus is a retinal scanning type display apparatus, and includes a low output laser whose operational current is less than that of a standard output laser; a shunting element that is connected in parallel with the low output laser; and a drive circuit that supplies a current to the low output laser and the shunting element. The drive circuit is a drive circuit for the standard output laser capable of adjusting a current value on a discrete basis in a range of an operational current that is higher than the operational current of the low output laser.
