Provided is an area drive-type light emitting device for image display in which PWM control is performed, wherein the reference current value and the PWM limiting condition are flexibly set according to the APL of an image. Specifically provided is a light emitting device for image display, wherein each of light emitting elements is provided with a light emitting unit (5) which is provided to correspond to each area, a PWM control unit (44) which PWM-controls a current to be supplied to the light emitting element, a control condition setting unit (45) which, according to the APL of image data, determines and updatably sets the PWM limiting condition for limiting the PWM value that is the duty ratio of the PWM control, and the reference current value that is the value of the current flowing to the light emitting element in response to turn-on of the PWM control, and a PWM value calculation unit (43) which on the basis of the image data, the PWM limiting condition, and the reference current value, calculates the PWM value of each area, and the PWM control unit (44) performs the PWM control on the basis of the reference current value and the calculated PWM value. |
