Abstract:
1. A display device comprising: a source line formed over a substrate; a gate line formed over the substrate extending across the source line; a pixel formed over the substrate at an intersection of the source line and the gate line, the pixel comprising: at least first and second thin film transistors wherein one of a source or drain of the first thin film transistor is electrically connected to the source line; a pixel electrode electrically connected to a source or drain of the second thin film transistor wherein the first and second thin film transistors are electrically connected in series between the pixel electrode and the source line; wherein a portion of the source line covers at least a portion of the first thin film transistor so that (1) the source or drain of the first thin film transistor which is connected to the source line and (2) at least a part of a channel region of the first thin film transistor are light shielded while both of (1) the source or drain of the second thin film transistor which is connected to the pixel electrode and (2) a channel region of the second thin film transistor, are not covered by any portion of the source line, and wherein a width of the source line is larger than a width of the channel region of the first thin film transistor, the width of the channel region taken along a direction perpendicular to a current flow direction of said channel region, and wherein the pixel electrode does not overlap any of the source line, the channel region of the first thin film transistor or the channel region of the second thin film transistor.
