  "textContent": "In the present invention, it is possible to precisely adjust the intensity of light emitted from a light source and ensure a dynamic range from high brightness to low brightness even in a field-sequential color drive format for turning light on and off at high speed. A light intensity detection signal (SFB) indicative of the intensity of light emitted by a light source (11) is acquired, and on the basis of the light intensity detection signal (SFB) and a set reference signal (SA), a comparison circuit (410) generates a comparison signal (SB) indicative of turning ON and OFF. Within a sub-frame period, a logic circuit (420) repeats turning ON/OFF based on a pulse signal inputted from the comparison circuit (410), and outputs a lighting signal (SD1) for causing the light source (11) to emit light in accordance with the reference signal (SA) which is a set value, and outputs a non-lighting signal (SD2) for causing the light source (11) to not emit light in accordance with a set value.",
