The display device includes a light source, and a control section adapted to generate a composite pulse width modulation signal using PWM1 having a first Duty ratio and PWM2 having a frequency higher than the frequency of PWM1, and control a light emitting state of the light source using the composite pulse width modulation signal. The control section corrects a second Duty ratio based on a difference between an expected value of luminance obtained when making the light source emit light using a virtual pulse width modulation signal, which is obtained by combining PWM1 and a pulse width modulation signal having the second Duty ratio, and a setting value of luminance based on the information related to the luminance of the light source, and then uses the second Duty ratio corrected as the Duty ratio of PWM2.
