A touch sensor includes a touch drive electrode, a touch detection electrode provided opposed to or side by side with the touch drive electrode and forming an electrostatic capacitance between the touch detection electrode and the touch drive electrode, and a touch detection circuit detecting a contact or proximity position of an object on the basis of a detection signal obtained from the touch detection electrode by applying a touch sensor drive signal to the touch drive electrode. The touch drive electrode is split into plural stripe-like electrode patterns. Applying the touch sensor drive signal to part of the electrode patterns forms a drive line at that time. The touch detection circuit performs a detection on the basis of a first detection signal obtained from a first drive line formed in a first period, and a second detection signal obtained from a second drive line formed in a second period.

An integrated circuit device as a first IC chip, a second IC chip, and a circuit board having a hole formed therein that is large enough to permit the second IC chip to be accommodated therein. The first and second IC chips are bonded together so as to be electrically connected together, and the first IC chip is mounted on the circuit board with the second IC chip accommodated in the hole formed in the circuit board. Here, one of the IC chips forming a chip-on-chip structure is accommodated in the hole formed in the circuit board, making further thickness reduction possible. Moreover, the obverse surfaces of the IC chips are located closer to the circuit board, making possible wireless mounting of the IC chips, despite forming a chip-on-chip structure, on the circuit board through connection using bumps. This helps reduce trouble due to inductance in a circuit that handles a high-frequency signal.

Embodiments of the invention provide an aircraft configuration that provides for increased engine noise shielding for community noise reduction, while still providing desirable aerodynamic attributes such as good spanwise lift distributions and good structural integration without excessive wing surface area. Specifically, the aircraft is configured to have a longer-chord inboard wing portion and a shorter-chord outboard wing portion. The aircraft engines are positioned in major part over the longer-chord inboard wing portions such that communities below the wing are at least partially shielded by the inboard wing portion from the engine noise. Embodiments of the invention also strategically position fowler flaps or other chord-increasing devices in the region of the wing proximate the engine. Since the fowler motion increases the effective chord of the wing as the flaps are extended, the flaps may be deployed to increase the shielding characteristics of the wing.

A LCD device has a LCD panel and a drive TCP for driving the LCD panel. Back light is guided to the rear surface of the LCD panel by a light-conductive sheet.

The conductive film is connected to a ground pattern of the printed circuit board which transfers signals to the drive TCP. The reflecting plate has both functions for reflecting back light and shielding the LCD panel against the noise generated by the printed circuit board.
