Abstract: To acquire a fine viewing angle property from oblique view fields in a lateral electric field type liquid crystal display device having liquid crystal initial alignment directions in two orthogonal directions. The absorption axis of the incident-side polarization plate and the absorption axis of the exit-side polarization plate are orthogonal to each other in both of the region I and the region II, and the liquid crystal layer, the in-cell retarder as an optical compensation layer, the A-plate, and the C-plate sandwiched therebetween are in parallel to either one of the absorption axes or orthogonal to the substrates. Therefore, the transmittance can be suppressed to be low and a fine black display can be acquired even when the display surface is viewed from the oblique view fields.

Abstract: A translucent liquid crystal display panel (2) includes pixel pairs as display units each formed by a left-eye pixel (4L) and a right-eye pixel (4R) and arranged in a matrix shape. A through hole (4Ld) arranged in a color layer (4Lc) of a color filter has a slit shape whose longitudinal direction is identical to the orientation direction of a cylindrical lens (3a) constituting a lenticular lens (3). Similarly, a through hole (4Rd) arranged in a color layer (4Rc) of a color filter has a slit shape whose longitudinal direction is identical to the orientation direction of the cylindrical lens (3a) constituting the lenticular lens (3). This suppresses the phenomenon that a hue is changed by a field-of-view angle and/or an external light condition on the translucent display panel capable of displaying an image directed to a plurality of viewpoints.

Abstract: When applying exogenous noise with a synchronizing signal or a transmission clock period, influence by the applied noise is inhibited from appearing on a liquid crystal display, without increasing circuit size. There are included: a timing controller generating a control signal of a scanning line driving gate driver and a control signal of a signal line driving source driver based on an input signal to be a reference inputted from the outside; an enable signal generation unit including a noise detecting circuit for detecting various items of noise entering the input signal and outputs an enable signal for turning OFF or ON the output of a gate driver control signal for a predetermined period based on output from the noise detecting circuit; and an image data output control circuit when detecting noise synchronized in a vertical period. The gate driver control signal is controlled to have an idle period.

Abstract: Disclosed is an active matrix liquid crystal display device with transverse electric field system, which improves afterimage. One electrode of many pixel comb electrodes is thicker in width than the other pixel comb electrode and common comb electrodes and is equal to a width of the common shield electrode covering through a second insulator film on video signal wirings. The display area is divided into two sub areas by the thick pixel comb electrode. The pixel comb electrode and the common comb electrode have the same number in each sub area. As the common shield electrode and the thick pixel comb electrode have the same width, the concentration of electric field can be eased near the pixel comb electrodes. The electric potential distribution becomes symmetric by symmetric configuration, reducing asymmetric lighting mode between frames. DC offset of the video signal after flicker adjustment decreases and the afterimage improves.

Abstract: An electronic apparatus includes a sensor system, an excitation generating unit which generates an intermittent sine wave signal and applies the same to the sensor system, and a demodulation unit which demodulates an amplitude modulated signal which is an output of the sensor system, in which the demodulation unit generates a demodulated signal using both a response of the sensor system in a period when the excitation generating unit outputs a sine wave and a response of the sensor system in a period, at least either immediately before or immediately after the above-mentioned period, when the excitation generating unit does not output a sine wave.

Abstract: Provided is to a display element capable of displaying an image on both sides thereof. In the display element, display operation is not constantly performed on both sides, and the display operation is, as necessary, switched to displaying only on one side without lowering the efficiency of a backlight or other light emitting bodies. The structure is made such that a planar light emitting body capable of emitting light in directions of both faces is sandwiched between two light control elements capable of electrically switching, from outside, between a light reflection state and a light transmission state. In such a structure, the faces of the light control elements serving as light reflection surfaces in the light reflection state face the planar light emitting body, and the planar light emitting body and the light control elements are further sandwiched between two liquid crystal elements.
