    Abstract: A tile display device includes element display devices, each including an element display panel which defines a display area and a panel driver disposed on a seam area surrounding the display area, and a coupling display device disposed on element display devices and coupled to the element display devices at neighboring seam areas. The coupling display device includes a boundary display panel on the neighboring seam areas, a coupler which couples the boundary display panel to the element display panels to provide a coupling panel structure, a boundary driver which drives the boundary display panel and a signal control center which drives the coupling panel structure.

    Abstract: A liquid crystal display includes first and second substrates, first and second alignment layers, and a liquid crystal layer between the alignment layers and including liquid crystal molecules. The liquid crystal molecules on a surface of the first alignment layer have a first pretilt angle in a direction which is vertical with respect to a horizontal plane surface parallel to the first substrate, and a first alignment angle in a direction which is horizontal with respect to a horizontal line parallel to the horizontal plane surface. The liquid crystal molecules on a surface of the second alignment layer have a second pretilt angle in the direction which is vertical with respect to the horizontal plane surface and different from the first pretilt angle, and a second alignment angle in the direction which is horizontal with respect to the horizontal line and different from the first alignment angle.

    Abstract: A liquid crystal including: a first substrate; a pixel electrode disposed on the first substrate and including a first subpixel electrode and a second subpixel electrode disposed in one pixel area; a second substrate facing the first substrate; and a common electrode disposed on the second substrate, wherein an area of a region occupied by the first subpixel electrode is less than an area of a region occupied by the second subpixel electrode. Each of the first and second subpixels has a cross-shaped stem and minute branches extending from it to improve side visibility quality and gray scale uniformity.
