Patent ID: 8736032

Claim:
An electronic device comprising: a circuit substrate; a first semiconductor package disposed on the circuit substrate; a second semiconductor package provided on the circuit substrate and spaced apart from the first semiconductor package; an insulating electromagnetic shielding structure provided on top and lateral surfaces of the first semiconductor package, the insulating electromagnetic shielding structure including: a first polarizer having a plurality of first polarizing elements arranged in a first pattern so as to have a first transmission axis; and a second polarizer having a plurality of polarizing elements arranged in a second pattern so as to have a second transmission axis orthogonal to the first transmission axis of the first polarizer; a conductive electromagnetic shielding structure provided on the circuit substrate and configured to cover the first and second semiconductor packages and the insulating electromagnetic shielding structure; and a vacant space between the first semiconductor package and the conductive electromagnetic shielding structure, wherein the vacant space is interposed between the insulating electromagnetic shielding structure and the conductive electromagnetic shielding structure.
