Claim Text:
1. A display device comprising: a light source; and a control section adapted to generate a composite pulse width modulation signal using a first pulse width modulation signal having a first duty ratio and a second pulse width modulation signal having a frequency higher than a frequency of the first pulse width modulation signal, and control a light emitting state of the light source using the composite pulse width modulation signal, wherein the control section corrects a second duty ratio, which is obtained based on a correspondence relationship between information related to luminance of the light source and a duty ratio of a pulse width modulation signal of the light source, 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 the first pulse width modulation signal 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 the control section obtains a corrected second duty ratio as a duty ratio of the second pulse width modulation signal.
