Abstract: A multilayer structure includes a touch sensor and an optical functional layer formed thereon. The optical functional layer includes a phase-difference layer and a linear polarization layer formed thereon on a side opposite to the touch sensor. The phase-difference layer which gives a phase difference to transmitted light has a laminated structure including a 1/4? phase-difference layer and a 1/2? phase-difference layer.

Abstract: An input device, disposed in front of a display device, includes a polarizing film, a ?/4 retardation film, and a touch sensor unit including first and second light transmissive films arranged farther from the outside of the input device than the polarizing film. Each of the first and second light transmissive films is formed of a film controlled such that it is approximately optically isotropic. The film exhibits birefringence caused by drawing in the machine direction upon manufacture such that the slow axis extends along the machine direction. The machine direction of the film is allowed to be orthogonal to that of the other film, thus allowing the slow axes to be orthogonal to each other in order to cancel out the slow axes such that the input device is generally isotropic.

Abstract: The screen of a liquid crystal panel is divided into two portions. In the divided screens (upper screen and lower screen), the corresponding common electrodes (each for one divided screen) are simultaneously driven. The driving signal (common signal C1) of the upper screen and the driving signal (common signal C2) of the lower screen change in one cycle of four frame periods. More specifically, in the above-mentioned cycle, the common signal C1 changes in a pattern (1→1→1→−1), and the common signal C2 changes in a pattern (1→−1→1→1) in synchronization with each other. Accordingly, upon comparison of the common signals C1 and C2, it appears that the signal having the same waveform is applied to the common electrodes while being out of phase with each other. Thus, a difference of the drive frequency between the upper screen and the lower screen is eliminated.
