Patent ID: 7027022

Claim:
An active matrix device comprising: a plurality of column lines formed over a substrate; a plurality of row lines extending over the substrate crossing said plurality of column lines to define a plurality of pixels in a matrix form; a plurality of switching elements over the substrate provided at intersections between said plurality of column lines and said plurality of row lines; a gate driver circuit over the substrate to drive said plurality of row lines; a source driver circuit over the substrate to drive said plurality of column lines, said source driver circuit including a plurality of analog buffer circuits corresponding to said plurality of column lines, wherein each of the analog buffer circuits comprises at least two circuits connected in parallel with respect to a corresponding one of the column lines, each of said circuits comprising at least one thin film transistor; and one of said at least two circuits of one of the analog buffer circuits is positioned in the same line along said column lines as one of said at least two circuits of another one of the analog buffer circuits.
