Abstract: To prevent dark unevenness at the corner portion of a screen, a provided is a liquid crystal display including a first pixel formed with a pixel electrode at a first angle in a Y-direction, wherein the pixel electrodes of top, bottom, left, and right adjacent pixels to the first pixel are at a second angle in a Y-direction. The absolute value of the first angle is equal to the absolute value of the second angle, and a sign of the first angle is opposite to a sign of the second angle The rotation direction of a liquid crystal when a voltage is applied to the pixel electrode is in the opposite directions between the adjacent pixels. Thus, it is possible to prevent ions included in the liquid crystal from flowing on the peripheral portion of a display region to prevent dark unevenness at the corner portion of the screen.

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.
