A display device includes a substrate including a display area in which pixels are arranged, and a non-display area in which dummy patterns are arranged, the non-display area surrounding the display area; an emission layer formed in the pixels and the dummy patterns; and a bank surrounding the emission layer, wherein in the non-display area, the bank includes multiple protrusions protruding from a side of the bank into the dummy pattern.

Methods of forming films of aligned carbon nanotubes on a substrate surface are provided. The films are deposited from carbon nanotubes that have been concentrated and confined at a two-dimensional liquid/liquid interface. The liquid/liquid interface is formed by a dispersion of organic material-coated carbon nanotubes that flows over the surface of an immiscible liquid within a flow channel. Within the interface, the carbon nanotubes self-organize via liquid crystal phenomena and globally align along the liquid flow direction. By translating the interface across the substrate, large-area, wafer-scale films of aligned carbon nanotubes can be deposited on the surface of the substrate in a continuous and scalable process.

The third and fourth directions are not parallel to the first and second directions, and the first, second, and third color areas are adjacent to each other in the third direction.
