Abstract: A circuit board structure and a display device, the circuit board structure includes a first circuit board, a second circuit board, a filling portion and an electromagnetic shield layer. The second circuit board has a thickness greater than that of the first circuit board. At least one corner portion forms at a joint of the first circuit board and the second circuit board. A connection line forms at a joint of the second circuit board and the first circuit board. The connection line is located at the corner portion. The filling portion fills the corner portion, an extending direction of the filling portion is identical to an extending direction of the corner portion. The extending direction is identical to a direction of the connection line. A thickness of a cross section of the filling portion perpendicular to the extending direction increases as a distance from the second circuit board decreases.
