A tiled display panel is provided. The tiled display panel includes multiple substrates, multiple liquid crystal pixels, multiple LED pixels, and multiple light-emitting circuits. Each substrate has a display region and a boundary region. The boundary region is located between the display region and the tiled boundary tiled by the substrates. The liquid crystal pixels are arranged in an array in the display region. The LED pixels are arranged in series in the boundary region. The light-emitting circuits are arranged in series in the boundary region along a first direction and are electrically connected to the LED pixels to provide multiple light-emitting signals for the LED pixels.
