Display device

A display device comprising:

• a light modulation device having an image forming area in which a plurality of pixels are arranged, and adapted to modulate incident light;
• and
• an illumination device adapted to illuminate the image forming area, characterized in that the illumination device has an effective dimming area in which a plurality of dimming parts each capable of individually controlling a light intensity of the light for illuminating the image forming area are arranged, wherein
• illumination areas illuminated by the light emitted from the dimming parts adjacent to each other out of the plurality of dimming parts partially overlap each other, and the light enters the light modulation device, and
• a position of a peak of an intensity distribution of the light emitted from the dimming part located on an outermost side of the effective dimming area is located one of on an outer edge of the image forming area and outside the image forming area, wherein
• the dimming parts are each configured so as to have a same shape, and in a case of defining a length in a first direction of the image forming area as L1, an interval of the peaks of the intensity distributions in the first direction of the light emitted from the plurality of dimming parts as p1, and a number of the dimming parts in the first direction of the effective dimming area as n1, p1 ×(n1−1)>L1 is fulfilled.
