1. A circuit substrate comprising:
a substrate body having a rectangular shape configured of four sides, the four sides including a first side and a second side extending in a first direction and opposing each other in a second direction, the four sides further including a third side and a fourth side extending in the second direction and opposing each other in the first direction, the substrate body having a top surface; and a plurality of electrodes mounted on the top surface of the substrate body, the plurality of electrodes including a first electrode positioned closest to the first side in the second direction and a second electrode positioned closest to the second side in the second direction among the plurality of electrodes, the first electrode having a first outer point positioned closest to the first side in the second direction and the second electrode having a second outer point positioned closest to the second side in the second direction, the plurality of electrodes defining a third outer point positioned closest to the third side in the first direction, a first imaginary line being defined as a line extending in the first direction and passing through the first outer point, a second imaginary line being defined as a line extending in the first direction and passing through the second outer point, and a third imaginary line being defined as a line extending in the second direction and passing through the third outer point, wherein a first area, a second area, and a third area are defined on the top surface with respect to the second direction, the first area being defined between the first side and the first imaginary line, the second area being defined between the second side and the second imaginary line, the third area being interposed between the first area and the second area in the second direction; and wherein a fourth area is defined on the top surface with respect to the first direction, the fourth area being defined between the third side and the third imaginary line; wherein the substrate body is formed with a first opening on the top surface such that an entirety of the first opening is positioned within an overlapping area where the first area and the fourth area overlap with each other; wherein the plurality of electrodes defines a fourth outer point positioned closest to the fourth side in the first direction, and a fourth imaginary line being defined as a line extending in the second direction and passing through the fourth outer point; and wherein the substrate body is further formed with a second opening at a position within an area defined between the fourth side and the fourth imaginary line in the first direction. |
