摘要： In a display device having driving circuits formed on the same substrate where pixels are formed, the lateral frame area of the display device is reduced. A gate signal line driving circuit is placed in parallel with a source signal line driving circuit, so that no driving circuits are provided in at least two opposing directions out of four directions with respect to a pixel region. With the above-described structure, the area the gate signal line driving circuit occupies in prior art is removed to reduce the width (side to side) of the display device. Therefore a display device that has a small frame area in the lateral direction can be provided.

摘要： To extend the range of distance (between a display screen and the eye of a viewer) with which the viewer can see 3D images with the naked eye and to reduce power consumption. A parallax barrier in a shutter panel is controlled to be arranged optimally in accordance with the distance between the viewer and a display panel. Specifically, an optimal parallax barrier is formed as appropriate by selectively switching a light-transmitting state and a light-shielding state of a plurality of optical shutter regions and a display element unit of pixels depending on a retention state. The retention state is realized in such a manner that at least one of electrodes between which a liquid crystal layer is sandwiched is connected to a transistor including a semiconductor layer containing an oxide semiconductor and the transistor is turned off.

摘要： An object of the invention is to suppress degradation in image quality of a liquid crystal display device which performs display by field sequential method and to reduce power consumption of a backlight. The highest brightness of a first color light in a pixel region is detected. Gamma correction is performed so that transmittance of a pixel of the region displaying the highest brightness of the first color light is set to maximum and transmittance of other pixel of the region is decreased in accordance with lowering of the first color light intensity, and the region is irradiated with the highest brightness of the first color light. Similarly, a second color light is irradiated in another region concurrently with irradiation of the first color, whereby input of an image signal and lighting of the backlight are performed simultaneously in every region of the pixel portion.
