Disclosed are a display panel and a display apparatus. The display panel includes: a first display region and a second display region. The first display region includes first pixel units arranged in an array, and the second display region includes second pixel units arranged in an array. A density of the first pixel units in the first display region is lower than a density of the second pixel units in the second display region. The display panel further includes an array substrate, which includes first data lines and second data lines extending in a column direction. The first data lines pass through the first display region. Each first data line is electrically connected to a sub-pixel of the first pixel unit in the first display region.
