| description | A display apparatus (1) includes display means for displaying an image, a light source (10) that irradiates light to the display means, and control means (13) for controlling the quantity of light of the light source (10) with pulse width modulation. The control means (13) controls the quantity of light of the light source (10) based on the ratio of the light-on period with pulse width modulation to the light-off period when the light source (10) is turned off. |
