Abstract: A display panel and a display apparatus using the same are disclosed. A display panel includes a base substrate including a plurality of pixel regions having corresponding gate lines and data lines, and a plurality of pads arranged at an outer periphery of the base substrate. The display panel further includes a group of subminiature light emitting diodes (LEDs) in each of the pixel regions to display an image. The subminiature LEDs in one of the pixel regions are arranged at locations within the one of the pixel regions based on a location of the one of the pixel regions with respect to a center of the base substrate.

Abstract: A multi-view display device is provided. The multi-view display device includes a display panel having a plurality of pixels disposed in a matrix arrangement, adjacent first and second pixels of the plurality of pixels constituting a group pixel; a barrier disposed on the display panel and having an opening that transmits light and a shielding portion that shields light; and a driver configured to selectively drive the display panel in a normal driving mode, a narrow viewing angle mode, and a multi-view mode by controlling signals applied to the first and second pixels. The opening is overlapped with the first pixel, and the shielding portion is overlapped with the second pixel.
