Abstract
The present disclosure provides a circuit board, an electrical component and a display apparatus. The circuit board includes a wiring pad which is divided into a plurality of sub-pads by bubble discharge paths, the bubble discharge paths intersect at a first point which is a geometric center of the wiring pad. By configuring bubble discharge paths with a shape of a straight line and as being intersected at the geometric center point of the wiring pad, the circuit board can discharge gas bubbles, generated when the wiring pad is soldered to a wiring terminal of other circuit board, from the geometric center point of the wiring pad to the edge thereof via the bubble discharge paths. Thus gas bubbles can be eliminated or reduced between the wiring pad and the wiring terminal when soldering, connection between the wiring pad and the wiring terminal can be more secure.
