According to one embodiment, a semiconductor device includes a circuit substrate, a semiconductor element, a sealing resin layer, and a conductive shielding layer. The viewing window in an exemplary method may move in accordance with detected change in the physical orientation of the display-device. A destination device on the packet network interfaces with the destination device through integrated service digital network procedures. An aperture clips portions of the collimated laser light striking the aperture outside the predetermined beam contour and reflects part or all of the clipped portion of the collimated laser light to a focusing lens.
