  • Publication number: 20130215373
    Abstract: In a three-dimensional display device using a liquid crystal lens, a planer electrode is formed on an upper substrate of the liquid crystal lens and strip-like electrodes are formed on a lower substrate of the liquid crystal display lens. The distance between the upper and lower substrates is provided by a bead. At this time, if the bead is present on the strip-like electrode, the lens formed thereon is distorted. In order to prevent this, a bump is formed to cover the strip-like electrode. The distance between the bump and the upper substrate is small, so that the bead is pushed out of the upper part of the strip-like electrode, preventing the lens from being distorted. As a result, it is possible to prevent the crosstalk caused by the lens distortion due to the presence of the bead on the strip-like electrode.

  • Publication number: 20130207944
    Abstract: Each of a plurality of timing controllers has a synchronization reference signal output terminal from which a synchronization reference signal is output and a synchronization reference signal input terminal to which the synchronization reference signal is input. A master timing controller outputs a predetermined signal of display signals which are input from an external device, from the synchronization reference signal output terminal of the master timing controller as the synchronization reference signal, and the synchronization reference signal is input to the synchronization reference signal input terminals of the master timing controller and a slave timing controller. Accordingly, a luminance difference can be prevented from occurring between divided regions of a display panel due to asynchronization between display signals input to respective timing controllers in a display device in which a plurality of timing controllers are used and the display panel is divided into a plurality of regions.

  • Publication number: 20130162927
    Abstract: A pixel electrode is formed on a TFT substrate, and a gate insulating film, an inorganic passivation film, a common electrode, and an alignment film are formed in this order thereover. A columnar spacer is formed to the counter substrate and is adapted to define a gap between the TFT substrate and the counter substrate. A through hole is formed in the gate insulating film of the TFT substrate, and the columnar spacer is disposed so as to cover a concave portion formed by the through hole. Since the area of contact between the columnar spacer and the TFT substrate is decreased, it is possible to suppress scraping of the alignment film and thus to prevent occurrence of bright spots.

  • Publication number: 20130162939
    Abstract: Columnar spacers are formed on a TFT substrate where a TFT circuit layer is formed. The TFT circuit layer has a TFT and a pixel electrode. A spacing between the TFT substrate and a counter substrate having a color filter, a black matrix, and an overcoat film is controlled by columnar spacers. The columnar spacers are inserted into an overcoat film formed on the counter substrate. Thus, the counter substrate and the TFT substrate are protruded inward. The substrates protruded inward are unlikely to be deformed. When an external pressure is applied or the front window or the like is bonded to the liquid crystal display panel with resin, the counter substrate is unlikely to be deformed by a stress applied by shrinkage on resin curing. Moreover, the number of columnar spacers can be properly set, thereby preventing the occurrence of low-temperature air bubbles.
