Abstract: An illuminating circuit structure includes a film sheet, an illuminant, a printed baseline layer, and a printed pad layer. The printed baseline layer includes a first baseline segment and a second baseline segment printed on the film sheet, while the printed pad layer includes a first bar pad and a second bar pad. For a first baseline head of the first baseline layer and a first pad head of the first bar pad, one of which extends along a first direction and the other of which extends along a second direction not parallel to the first direction. Therefore, the first baseline segment and the first bar pad achieve electrical connection despite of an existed print shifting. Similarly, a second baseline head of the second baseline layer and a second pad head of the second bar pad also can achieve electrical connection despite of an existed print shifting.
