Abstract

A display device for controlling light intensity is provided. The display device has a pair of glass substrates disposed in parallel so as to face each other, and first and second transparent electrodes each arranged as stripes on the inner surfaces of the glass substrates, respectively, and extend orthogonally to each other and to which voltages are applied. A dielectric layer is disposed between the first transparent electrode and the second transparent electrode. The intensity of light transmitting the display device is controlled by controlling the density of electrons charged in part of at least one of the first and second transparent electrodes according to the applied voltage and thus reflecting light incident on the electrodes in which the electrons are charged.
