    摘要: PROBLEM TO BE SOLVED: To provide an integrated circuit built-in device capable of preventing electromagnetic waves which have a harmful effect on the outside of the device from leaking to the outside of the device while preventing an increase in device weight.SOLUTION: The integrated circuit built-in device (display device) comprises: a first wiring board 3 on which a first control device M1 (microcomputer) is mounted; and a second wiring board 11 which faces the first wiring board 3 and on which a second control device M2 (graphic controller) is mounted. The first control device M1 and the second control device M2 which emit electromagnetic waves to the outside of the device are located between the first wiring board 3 and the second wiring board 11. The first wiring board 3 has a first electromagnetic shielding part S1, and the second wiring board 11 has a second electromagnetic shielding part S2. When seen from a normal direction of an opposite side of the wiring board, the first electromagnetic shielding part S1 and the second electromagnetic shielding part S2 are overlapped, and the first control device M1 and the second control device M2 are located in the overlapped area.
