ABSTRACT:
An electro-optical display device comprises: an active matrix unit including a substrate having one surface and the other surface and a plurality of switching elements provided on the one surface of the substrate; a shutter unit provided on the active matrix unit, and a first microlens array provided on the other surface of the substrate of the active matrix unit, the first microlens array having a plurality of microlenses formed on the other surface of the substrate in a corresponding relationship with the plurality of window portions. The shutter unit is comprised of: a base provided so as to oppose the one surface of the substrate, the base having a plurality of window portions provided in a corresponding relationship with the plurality of switching elements; movable plates provided above the plurality of window portions so as to be displaceable relative to the base, the movable plates opening and closing the plurality of window portions to obtain an opening state and a closing state of each of the plurality of window portions; and driving means for displacing the movable plates and switching the opening state and the closing state of each of the plurality of window portions. The electro-optical display device is capable of using light with increased utilization efficiency and displaying a high quality image, while exhibiting enhanced reliability. Further, an electronic device provided with the electro-optical display device is also provided.
