摘要： The present disclosure provides a display panel having sub-pixels that include light-emitting sub-pixels and compensation sub-pixels located in a first display area. A density of sub-pixels in a first semi-transmissive area and in a second semi-transmissive area is smaller than a density of sub-pixels in a second display area. The first display area, the first semi-transmissive area, and the second semi-transmissive area have a same density of light-emitting sub-pixels. First pixel columns are provided in the first display area. Second pixel columns are provided in the second display area. A first data line passes through the first pixel column, and a second data line passes through the second pixel column.
