Active matrix electro-optic display device with light shielding layer and projection and color employing same

Image Number 6 for United States Patent #5237436.

The thin film switch of a pixel of an active matrix liquid crystal light valve is shielded from light by adding a light shielding layer of amorphous germanium or germaniums nitride in the interpixel area surrounding the pixel electrodes. Such active matrix displays are advantageously employed in a color projection TV to produce the separate red, blue and green components of a full color display.
