1. A circuit substrate, comprising:
a base material, having an upper side and a lower side opposite to each other in a length direction;
a first electrode, extending and being configured on the base material along the length direction;
a second electrode, configured beside the first electrode and comprising a first portion and a second portion connected to each other, wherein the first portion is configured on the base material along the length direction, the second portion is configured on the base material along a width direction and is located between the upper side and the first electrode, and a cross-sectional width of the first portion becomes larger from the lower side to the upper side;
a drain electrode or a source electrode extending and configured on the base material along the length direction; and
a gate electrode extending and configured on the base material along the length direction, wherein the gate electrode is located between the drain electrode or the source electrode and the first electrode, and viewed from a top view, an outline of the drain electrode or the source electrode and an outline of the gate electrode are both rectangular.
