ABSTRACT:
A liquid crystal display is disclosed having switching devices corresponding to pixel electrodes formed on the same semiconductor layer that has a drive circuit therein. The drive circuit is formed on the semiconductor layer in a single crystal semiconductor region and the switching devices are formed either in a second single crystal semiconductor region or in a non-single crystal semiconductor region. The second single crystal semiconductor region or the non-single crystal semiconductor region bearing the switching devices has a higher density of defects than the first semiconductor region.
