Abstract: The reliability of a display device with an input device is improved. A plurality of detection electrodes (input position detection electrodes) forming an electrostatic capacity between them and a common electrode of a display device to detect an input position are formed on a different substrate from substrates configuring the display device. Moreover, a polarizing plate and the substrate on which the plurality of detection electrodes are formed are adhesively fixed via, for example, an adhesive layer so that the plurality of detection electrodes are fixed so as to be separated apart from the display device. Thus, a distance between electrodes (the detection electrode and a driving electrode) for detecting an input position can be set separately from a thickness of the display device, and therefore, reduction in detection sensitivity (detection reliability) for the input position due to increase in the electrostatic capacity can be suppressed.

Abstract: In a three dimensional display device of a parallax barrier system in which an IPS-mode liquid crystal display panel is used as a liquid crystal display panel for displaying images and a TN-mode liquid crystal panel is used as a parallax barrier panel, alignment axes of a counter substrate and a barrier substrate constituting the parallax barrier panel are set to 45 degrees and 135 degrees, respectively, with respect to a horizontal direction of a screen. This allows an improvement in the viewing angle characteristics of the parallax barrier panel and an improvement in the viewing characteristics of the overall three dimensional display device of the parallax barrier system. Thus, even when the line of sight moves, crosstalk between an image for a right eye and an image for a left eye can be prevented thereby allowing a viewer to recognize excellent three dimensional images.
