Abstract

In a circuit board disposed in parallel to a fixing plane, a guard spacer (abutting member) is disposed on a multi-layer printed circuit board on the side of the fixing plane to suppress deformation of the multi-layer printed circuit board to prevent short circuit if an impact is applied to the circuit board. The guard spacer may be a dummy electronic component or a plate member. An image display using the circuit board is also disclosed.
