A display device comprises a plurality of light modulating elements being arranged in an array. In the display device, an image is displayed by driving the light modulating elements and each of the light modulating elements has a pair of substrates which are spaced apart from each other; a fluid which is enclosed in a sealed space formed by a gap between the substrates; and a driving section which deforms the fluid in the sealed space to control an area of the fluid in the sealed space, the area extending in a face of at least one of the substrates, thereby adjusting an amount of transmitted light or reflected light.
