Active matrix display and electrooptical device

摘要

A display device having 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 and gate lines, the pixel having: first and second thin film transistors where 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 where the first and second thin film transistors are electrically connected between the pixel electrode and the source line; where a portion of the source line covers a portion of the first thin film transistor, where a width of the source line is larger than a width of a channel region of the first thin film transistor, and where the pixel electrode does not overlap the source line.
