An electro-optic display comprising at least two separate layers of electro-optic material, with one of these layers being capable of displaying at least one optical state which cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.

One embodiment of the present invention provides a highly reliably display device in which a high mobility is achieved in an oxide semiconductor. A first oxide component is formed over a base component. Crystal growth proceeds from a surface toward an inside of the first oxide component by a first heat treatment, so that a first oxide crystal component is formed in contact with at least part of the base component. A second oxide component is formed over the first oxide crystal component. Crystal growth is performed by a second heat treatment using the first oxide crystal component as a seed, so that a second oxide crystal component is formed. Thus, a stacked oxide material is formed. A transistor with a high mobility is formed using the stacked oxide material and a driver circuit is formed using the transistor.

The capacitor includes multiple parallel partial capacitors each having an interdigitated structure in a respective metallization level. The metallizations (aluminum and/or copper) are opaque and the capacitor therefore protects the transistor from light, the level of protection being increased with the number of metallization levels used to form the interdigitated structures.

An enclosure that maintains the environment of one or more optical crystals and allows efficient frequency conversion for light at wavelengths at or below 400 nm with minimal stress being placed on the crystals in the presence of varying temperatures. Efficient conversion may include multiple crystals of the same or different materials. Multiple frequency conversion steps may also be employed within a single enclosure. Materials that have been processed specifically to provide increased lifetimes, stability, and damage thresholds over designs previously available are employed. The enclosure allows pre-exposure processing of the crystal(s) such as baking at high temperatures and allowing real time measurement of crystal properties.

Furthermore, the common bus lines can be positioned in such a manner so that they do not further reduce the aperture of the display. More specifically, the common bus lines can be positioned above or below existing elements of the display that are already opaque. Thus, adding the common bus lines need not reduce the aperture.
