A laser scanning display device comprising: a plurality of light sources (11, 12, 13) of different emission colors that emits a laser light with a light intensity corresponding to a current supplied; a storage means that stores a gradation level of a plurality of steps corresponding to a plurality of reference light intensities as a reference, and current control data associating with the gradation level and indicating a current supplied to the light source; a light source control means that adjusts a current supplied to the light source by switching the gradation level based on an image signal; a dimmer means that modulates the light intensity of the laser light emitted from the light source wherein the dimmer means is configured to be adjusted to different dimming values; a first light detection means that detects the light intensity of the laser light before entering the dimmer means; a second light detection means that detects the light intensity of the laser light after entering the dimmer means; a scanning means that displays a predetermined image in a display unit by scanning the laser light after entering the dimmer means; a gradation correction means that calculates a current-light intensity characteristic of each color of the light source, based on the light intensity of the light source detected by the first light detection means by supplying a predetermined current from the light source control means, and corrects the current control data stored in the storage unit, based on the calculated current-light intensity characteristic; and a toning correction means that detects the light intensity of the light source detected by the second light detection means by supplying a predetermined current from the light source control unit, compares the detected light intensities of each color of the light source, and adjusts a white balance by correcting the current control data. a plurality of light sources (11, 12, 13) of different emission colors that emits a laser light with a light intensity corresponding to a current supplied; a storage means that stores a gradation level of a plurality of steps corresponding to a plurality of reference light intensities as a reference, and current control data associating with the gradation level and indicating a current supplied to the light source; a light source control means that adjusts a current supplied to the light source by switching the gradation level based on an image signal; a dimmer means that modulates the light intensity of the laser light emitted from the light source wherein the dimmer means is configured to be adjusted to different dimming values; a first light detection means that detects the light intensity of the laser light before entering the dimmer means; a second light detection means that detects the light intensity of the laser light after entering the dimmer means; a scanning means that displays a predetermined image in a display unit by scanning the laser light after entering the dimmer means; a gradation correction means that calculates a current-light intensity characteristic of each color of the light source, based on the light intensity of the light source detected by the first light detection means by supplying a predetermined current from the light source control means, and corrects the current control data stored in the storage unit, based on the calculated current-light intensity characteristic; and a toning correction means that detects the light intensity of the light source detected by the second light detection means by supplying a predetermined current from the light source control unit, compares the detected light intensities of each color of the light source, and adjusts a white balance by correcting the current control data.
