Disclosed is a display device comprising a light-shielding plate including a metal thin film formed on a first principal surface of an optical waveguide plate for introducing the light thereinto and including light-transmitting sections formed at portions corresponding to picture elements to make penetration through the optical waveguide plate, and shutter sections provided opposingly to a second principal surface of the light-shielding plate, for selectively intercepting the light transmitted through the light-transmitting sections in accordance with an input signal. The shutter sections include actuator elements provided corresponding to the large number of light-transmitting sections so that the light to be transmitted through the light-transmitting sections is intercepted substantially in synchronization with the operation of the actuator elements. Accordingly, it is possible to improve the contrast and improve the image quality of a displayed image.
