摘要： A display panel includes two or more gate layers including a plurality of gate patterns extending in a first direction and one or more source-drain layers including a plurality of source-drain patterns extending in a second direction crossing the first direction. The gate patterns of the two or more gate layers are curved or bent along a hole surrounding area corresponding to a periphery of a hole in an active area. The source-drain patterns of the one or more source-drain layers are curved or bent along the hole surrounding area. The gate patterns of at least one of the two or more gate layers overlap the source-drain patterns of at least one of the one or more source-drain layers in a thickness direction of the display panel in the hole surrounding area.
