Abstract:
1. A circuit substrate, comprising: a base; and a plurality of conductive traces disposed on a same layer of the base and including at least a first conductive trace and a second conductive trace, wherein the circuit substrate has a cut region, and the cut region is a long strip, the cut region having a first end portion in the longitudinal direction and two sides, the first conductive trace has a first portion, a second portion and a third portion, in which the second portion is connected between the first portion and the third portion, the first portion of the first conductive trace is connected to the first end portion of the cut region and an included angle between a rim of the first end portion of the cut region and the first portion of the first conductive trace is 75° to 105°, and the second conductive trace is connected to one of the two sides, and the third end portion of the first conductive trace is substantially parallel to the second conductive trace.
