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: An etchant composition including a persulfate, a four-nitrogen ring compound, a carbonyl ring compound having two or more carbonyl groups, and water, and having a weight ratio of the four-nitrogen ring compound and the carbonyl ring compound of about 1:0.1 to about 1:2. The etchant composition may etch a multilayer of titanium/copper and may be used for manufacturing a metal pattern and an array substrate having excellent properties of an etched pattern.

Abstract: A display device includes a first display panel, a second display panel, and an optical member. The first display panel includes a first substrate and a first cover member on the first substrate. The second display panel is coupled to a first side of the first display panel, and includes a second substrate and a second cover member on the second substrate. The optical member is in a groove defined by the first and second cover members at a boundary of the first and second display panels.
