Abstract: An IPS-mode transflective LCD device includes an array of pixels each including a reflective region and a transmissive region juxtaposed. The reflective region operates in a normally-white mode, and the transmissive region operates in a normally-black mode. A common data signal is supplied to the reflective region and transmissive region, whereas the common electrode signal in the transmissive region is an inverted signal of the common electrode signal in the reflective region, to thereby obtain similar gray-scale levels.

Abstract: The liquid crystal display device includes a transparent electrode formed in a plan form and a strip or strips transparent electrode disposed thereon via an insulating film, and controls display by rotating the liquid crystal aligned substantially in parallel to a substrate within a plane that is substantially in parallel to the substrate by an electric field between the both electrodes. Each pixel constituting the display is divided into two regions, the extending directions of the strip electrode in each of the regions are orthogonal, the alignment azimuths of the liquid crystal of each of the regions are orthogonal, and the angles formed between the extending directions of the strip electrode and the alignment azimuth of the liquid crystal are the same.

Abstract: A display panel is attached to a front plate which is disposed at a front surface side of the display panel, with an intermediate member interposed therebetween. A chassis accommodates the display panel in a state in which an opening edge of the chassis comes into contact with the front plate and an inner side surface of the chassis comes into contact with a side surface of the intermediate member. The opening edge of the chassis comes into contact with the front plate to position the display panel and the chassis in the thickness direction of the display panel. The inner side surface of the chassis comes into contact with the side surface of the intermediate member to position the display panel and the chassis in a direction along a display surface of the display panel.

Abstract: To provide a naked-eye type stereoscopic display device which can achieve a fine stereoscopic display property while achieving high-definition display and high yield. An aperture part includes overlapping regions which overlap with an aperture part or another aperture part neighboring to each other in a second direction and a non-overlapping region which does not overlap. Provided that a light amount emitted from a linear aperture of the aperture part in parallel to a second direction is “longitudinal light amount”, the non-overlapping region includes longitudinal light amount fluctuating regions where the longitudinal light amount changes continuously from roughly a center of the aperture part towards both ends of the first direction, respectively. The sum of the longitudinal light amounts of the two overlapping regions overlapping with each other at a same position in the first direction is larger than the longitudinal light amount in roughly the center of the aperture part.

Abstract: An LED driving circuit, an LED driving method, and a liquid crystal display device, which prevent deterioration of display quality by effectively shortening the time required for starting the LED backlight and stabilizing the driving operations are provided. The LED driving circuit for controlling an LED circuit constituted with one LED or two or more LEDs includes: a duty ratio adjusting circuit unit which generates/outputs adjusting signals for adjusting drive of the LED based on a PWM dimming signal inputted from outside; and a booster circuit unit which applies driving voltages to the LED circuit according to the adjusting signal outputted from the duty ratio adjusting circuit unit. The duty ratio adjusting circuit unit sets the adjusting signal to have a larger duty ratio than that of the PWM dimming signal within an adjusting period set after the power is supplied until the LED circuit starts to connect electrically.

Abstract: For improved high-definition of liquid crystal display devices and the use thereof in bright places, luminance of backlights is being increased. Thus, when a light-shielding layer is employed for suppressing a light leakage current, characteristic fluctuations of transistors are caused, which may result in showing faulty display. In a dual-gate thin film transistor having a floating light-shielding layer, the layout is designed in such a manner that the film thickness of the insulating layer is equal to or more than 200 nm and equal to or less than 500 nm and that Sg/Sd becomes 4.7 or more, provided that an opposing area between the light-shielding layer and a drain region in a place at the outermost side of the active layer is Sd and the opposing area between the light-shielding layer and the gate electrode is Sg.
