abstract:

A thin-film transistor includes a gate electrode having first and second
gate electrode edges on opposed sides, and a drain electrode having a
first edge that overlaps the first gate electrode edge, and a second edge
that overlaps the second gate electrode edge. A diode array is fabricated
by successive deposition of a conductive layer, a doped semiconductor
layer and an undoped semiconductor layer adjacent to the substrate. A
display pixel unit provides reduced capacitative coupling between a pixel
electrode and a source line. The source line includes an extension that
provides a source for the transistor. A patterned conductive portion is
disposed adjacent to the source line. Another display pixel unit provides
reduced pixel electrode voltage shifts using a source line and a balance
line.
