Patent ID: 7024094

Claim:
A display device comprising: a first plate, a paired optical waveguide comprising a first optical waveguide and a second optical waveguide, a first transparent electrode, and a second electrode which faces the first transparent electrode, the second optical waveguide comprising an electroresponsive material formed between the first transparent electrode and the second electrode which face each other, wherein at least one of the first optical waveguide and the second optical waveguide is formed in close contact with the first plate, and the first and second optical waveguides are disposed in close contact with or near each other so that light guided to the first optical waveguide is led to and leaks through the second optical waveguide, and wherein the electroresponsive material is transparent against the guided light, but changes in form when voltage is applied between the first transparent electrode and the second electrode to thereby scatter the guided light of the second optical waveguide and emit the scattered light outside as pixels.
