ABSTRACT:
A liquid crystal display includes a base plate having a plurality of pixels on a surface thereof with the pixels arranged in an array of spaced rows and columns. Each of the pixels includes a substantially rectangular region of polycrystalline silicon. A separate select line of polycrystalline silicon extends over and across the polycrystalline silicon regions of each row of pixels adjacent one side of the polycrystalline silicon region. The select lines has two extensions extending over and along two opposite sides of each polycrystalline silicon region. A layer of a dielectric material extends between the polycrystalline silicon regions and the first lines and the extensions of the first lines. Each of the first lines and its extensions forms a capacitor with the respective polycrystalline silicon region of each pixel. Data lines extend along the rows of the pixels and are electrically connected to each polycrystalline silicon region in its respective column of pixels.
