Electro-optical apparatus utilizing at least three electro-optical modulating device to provide a sythesized color image and method of driving same

Claim 1

An electro-optical device comprising: at least three electro-optical devices, each of said three electro-optical devices comprising a transparent conductive film provided on a first substrate, a photoconductor provided on said transparent conductive film, a dielectric film provided on said photoconductor and capable of intercepting a light, a second substrate provided with a transparent conductive film and orientation control means thereon, and an electro-optical modulating layer provided between said first substrate and said second substrate; means capable of emitting an image light; means for distributing said image light into at least three light components; at least three optical shutters capable of transmitting and intercepting said at least three light components, respectively, said at least three light components transmitted by said at least three optical shutters being incident on the respective first substrates of said at least three electro-optical devices, respectively; a light source; at least three filters for separating the light emitted from said light source into at least three different color light components respectively; and means for synthesizing at least three light patterns reflected from said at least three electro-optical devices, wherein said at least three different color light components are incident on the second substrates of said at least three electro-optical devices and reflected from said at least three electro-optical devices to produce said at least three light patterns.
