Abstract
A display device capable of obtaining stable light output even in a state of low brightness and capable of displaying desired display colors is provided. An output control means (80) causes image-forming light to be emitted from a laser source (10) on the basis of image information when the scanning position of an RGB laser beam according to a scanning means is within a display range (20), and causes detection light to be emitted from the laser source (10) when the scanning position is outside the display range. In addition, the output control means (80): changes the drive current of the laser source (10) according to a first current value that is less than a threshold current value, and second and third current values that are greater than or equal to the threshold value, when the scanning position according to the scanning means (20) is outside the display range; and drives the laser source (10) according to the drive current obtained by calculating the current-light output characteristics on the basis of the light intensity detected by a laser beam detection unit (40).
