Claim:
1. A semiconductor device comprising: a first transistor, a second transistor, and a third transistor; a capacitor; a pixel electrode; a potential line; a gate line; and a signal line, wherein one of a source and a drain of the first transistor is electrically connected to one of a source and a drain of the second transistor, wherein the one of the source and the drain of the first transistor is electrically connected to a first electrode of the capacitor, wherein the one of the source and the drain of the first transistor is electrically connected to the pixel electrode, wherein one of a source and a drain of the third transistor is electrically connected to a second electrode of the capacitor, wherein the other of the source and the drain of the first transistor is electrically connected to the potential line, wherein a gate of the third transistor is electrically connected to the gate line, wherein the other of the source and the drain of the third transistor is electrically connected to the signal line, wherein a channel forming region of the first transistor comprises a first part and a second part, wherein a direction of a channel length of the first part crosses to a direction of a third part of the gate line, wherein a direction of a channel length of the second part crosses to a direction of a fourth part of the source line, wherein a direction of a channel width of the first part crosses to the direction of the fourth part of the source line, and wherein a direction of a channel width of the second part crosses to the direction of the third part of the gate line.
