Title: Light modulating device wherein colored/uncolored state of color filter is electrically controlled by second electrode and third electrode

Abstract: A light modulating device includes: a first substrate on which a first electrode layer and a light amount control layer are deposited in this order; a second substrate on which a second electrode layer and a color filter layer are deposited in this order, the second substrate opposing the first substrate; and a third electrode layer interposed between the light amount control layer and the color filter layer, wherein a plurality of picture elements are defined in a matrix pattern by the first electrode layer and the third electrode layer. An amount of light transmitted through the light amount control layer is electrically controlled by the first electrode layer and the third electrode layer. A colored/uncolored state of the color filter layer is electrically controlled by the second electrode layer and the third electrode layer.
