In some embodiments, a respective spacing, measured along the first direction of extent, of the picture elements from a second reference line that extends rectilinearly along the second direction of extent can vary irregularly along the second direction of extent. The second reference line can in particular also correspond to an imaginary line extending along the second direction of extent over the panel. The spacings of the picture elements from the second reference line that are related to the first direction of extent can in particular vary irregularly along a plurality of picture elements and/or a respective spacing, measured along the first direction of extent, between the second reference line and picture elements adjacent to the second reference line can vary irregularly along the second direction of extent. Furthermore, the respective spacing of the picture elements from the second reference line can vary irregularly along a reference path, which amounts to at least 5 cm and/or comprises at least 20 picture elements, along the second direction of extent and/or the respective spacing can vary irregularly over the total extent of the panel along the second direction of extent.
