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.
