An optical modulating fine aperture array device is provided. The device includes a spatial light modulation unit provided with at least one light capacity cell arranged in a shape of a matrix, wherein each of the light capacity control cells is capable of individually controlling a degree of an inputted light which passing therethrough. A micro-lens array is provided with at least one micro-lens arranged in a shape of a matrix, wherein each of the micro-lenses condenses the light passing through each of the light capacity control cells. A substrate is made of an optical transparent material. The micro-lens array is attached to one side of the substrate. An aperture array is arranged on other side surface of the substrate and provided with at least one fine aperture. An immersion thin film layer is made of an optically transparent dielectric, including and formed to have a predetermined thickness from the aperture array.
